Question 1 |

With what number must 3.475817 be multiplied in order to obtain the number 34,758.17?

A | 100 |

B | 1,000 |

C | 10,000 |

D | 100,000 |

Question 1 Explanation:

The correct answer is (C). The decimal must be moved four places to the right. To do this, we must multiply by a number with four zeroes. The correct answer is 10,000.

Question 2 |

How much greater is the value of 3

*x*+ 5 than the value of 3*x*− 7?A | 8 |

B | 10 |

C | 12 |

D | 14 |

Question 2 Explanation:

The correct answer is (C). The easiest way to do this is to pick a number for

3(3) + 5

= 9 + 5

= 14

3(3) − 7

= 9 − 7

= 2

The correct answer is 14 − 2 = 12.

*x*. Let’s say*x*= 3.3(3) + 5

= 9 + 5

= 14

3(3) − 7

= 9 − 7

= 2

The correct answer is 14 − 2 = 12.

Question 3 |

Which of the following is NOT a factor of 90?

A | 5 |

B | 6 |

C | 12 |

D | 15 |

Question 3 Explanation:

The correct answer is (C). A factor must divide evenly into its multiple. 12 cannot be a factor of 90 because 90 divided by 12 = 7.5.

Question 4 |

Lisa and Robert have taken the same number of photos on their school trip. Lisa has taken 3 times as many photos as Claire and Robert has taken 12 more photos than Claire. How many photos has Claire taken?

A | 6 |

B | 8 |

C | 10 |

D | 12 |

Question 4 Explanation:

The correct answer is (A). Translate the information in the question from “English” to “Math.”

L = R

L = 3C

R = C + 12

We can substitute R for L in the second equation: R = 3C. If R is equal to both 3C and C + 12, we can say 3C = C + 12, and solve for C.

3C = C + 12

2C = 12

C = 6

L = R

L = 3C

R = C + 12

We can substitute R for L in the second equation: R = 3C. If R is equal to both 3C and C + 12, we can say 3C = C + 12, and solve for C.

3C = C + 12

2C = 12

C = 6

Question 5 |

The sum of 7 numbers is greater than 140 and less than 210. Which of the following could be the average (arithmetic mean) of the numbers?

A | 20 |

B | 26 |

C | 30 |

D | 34 |

Question 5 Explanation:

The correct answer is (B). The formula for the average of a set of numbers is the sum of the numbers divided by the number of terms.

Avg = 140 / 7

Avg = 20

Avg = 210 / 7

Avg = 30

Therefore, the sum must be between 20 and 30.

Avg = 140 / 7

Avg = 20

Avg = 210 / 7

Avg = 30

Therefore, the sum must be between 20 and 30.

Question 6 |

The hour hand of a watch rotates 30 degrees every hour. How many complete rotations does the hour hand make in 6 days?

A | 8 |

B | 10 |

C | 12 |

D | 14 |

Question 6 Explanation:

The correct answer is (C). There are 360 degrees in a complete circle, so 360/30 = 12 hours to make one full circle. In 6 days there are 24 hours x 6 = 144 hours total. The total number of rotations will be 144/12 = 12.

Question 7 |

Which of the following expressions is equal to 3

^{8}when*p*= 3^{5}?A | 6 p |

B | 9 p |

C | 16 p |

D | 27 p |

Question 7 Explanation:

The correct answer is (D). 3

^{8}= 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3, or 3^{5}x 3^{3}=*p*x 3^{3}*p*x 3^{3}= 27*p*Question 8 |

If

*y*+ 3*y*+ 5*y*= −18, then what is the value of*y*?A | −2 |

B | −1 |

C | 0 |

D | 1 |

Question 8 Explanation:

The correct answer is (A). When terms with the same variable are in the same equation, they can be combined.

9

*y*+ 3*y*+ 5*y*= 7*y*9

*y*= −18*y*= −18/9*y*= −2Question 9 |

If b does not equal zero, and ab = b/4, what is the value of a?

A | 1/8 |

B | 1/4 |

C | 1/3 |

D | 1/2 |

Question 9 Explanation:

The correct answer is (B). To solve for a, divide both sides of the equation by b: ab = b/4

(ab)/b = (b/4)/b

a = (b/4)*1/b

a = 1/4

(ab)/b = (b/4)/b

a = (b/4)*1/b

a = 1/4

Question 10 |

If a store adds 50 chairs to its current inventory, the total number of chairs will be the same as three-halves the current inventory of chairs. If the manager wants to increase the current inventory by 40%, what will the new inventory of chairs be?

A | 40 |

B | 60 |

C | 100 |

D | 140 |

Question 10 Explanation:

The correct answer is (D). This word problem requires careful translation. Let’s say t = total current inventory of chairs. The first sentence states that 50 + t = (3/2)t. First solve for the current inventory:

50 + t = (3/2)t

50 = (3/2)t − t

50 = (1/2)t

100 = t

The manager wants to increase this by 40%.

40% of 100 is 40, so the new inventory will be 140.

50 + t = (3/2)t

50 = (3/2)t − t

50 = (1/2)t

100 = t

The manager wants to increase this by 40%.

40% of 100 is 40, so the new inventory will be 140.

Question 11 |

On a map, the length of the road from Town F to Town G is measured to be 18 inches. On this map, ¼ inch represents an actual distance of 10 miles. What is the actual distance, in miles, from Town F to Town G along this road?

A | 580 |

B | 720 |

C | 960 |

D | 1140 |

Question 11 Explanation:

The correct answer is (B). Here we are given a ratio: ¼ inch on the map = 10 miles, so 1 inch on the map = 40 miles. If the map-distance between the towns is 18 inches, then the actual distance must be 18 x 40 = 720.

Question 12 |

How many 1/3 pound paperback books together weigh 25 pounds?

A | 35 |

B | 50 |

C | 60 |

D | 75 |

Question 12 Explanation:

The correct answer is (D). If each book weighs 1/3 pound, then 1 pound = 3 books. We can set up a proportion to solve: 1 pound / 3 books = 25 pounds / x books. Now cross-multiply:

(1)(x) = (3)(25)

X = 75

(1)(x) = (3)(25)

X = 75

Question 13 |

If 12.5 is

*y*percent of 250, what is 20*y*?A | 0.05 |

B | 0.5 |

C | 1 |

D | 1.5 |

Question 13 Explanation:

The correct answer is (C).

250

20 * 0.05 = 1

250

*y*= 12.5*y*= 5%20 * 0.05 = 1

Question 14 |

Each year, a cyber café charges its customers a base rate of $25, with an additional $0.30 per visit for the first 50 visits, and $0.10 for every visit after that. How much does the cyber café charge a customer for a year in which 72 visits are made?

A | 36.60 |

B | 42.20 |

C | 47.80 |

D | 51.10 |

Question 14 Explanation:

The correct answer is (B). Translate the information into arithmetic. The café charges $25 + $0.30(first 50) + $0.10(additional after 50). For 72 visits there are 50 visits with an additional 22 visits.

$25 + $0.30(50) + $0.10(22)

=$25 +$15 + $2.20

=$42.20

$25 + $0.30(50) + $0.10(22)

=$25 +$15 + $2.20

=$42.20

Question 15 |

If Jill needed to buy 9 bottles of soda for a party in which 12 people attended, how many bottles of soda will she need to buy for a party in which 8 people are attending?

A | 6 |

B | 8 |

C | 10 |

D | 12 |

Question 15 Explanation:

The correct answer is (A). We can set up a proportion to solve:

9 bottles / 12 people = x bottles / 8 people.

Cross-multiply to solve a proportion:

(9)(8) = (12)(x)

72 = 12x

6 = x

9 bottles / 12 people = x bottles / 8 people.

Cross-multiply to solve a proportion:

(9)(8) = (12)(x)

72 = 12x

6 = x

Question 16 |

Steve bought a total of 6 packages of pens, and each package contained either 3 or 7 pens. If exactly 4 of the packages Steve bought contained 7 pens, how many pens did Steve buy?

A | 17 |

B | 21 |

C | 34 |

D | 42 |

Question 16 Explanation:

The correct answer is (C). If Steve bought 4 packages of 7 pens and 6 packages total, then he must have purchased 2 packages of 3 pens.

4(7) + 2(3) = 28 + 6 = 34

4(7) + 2(3) = 28 + 6 = 34
