1. If y = 4 and x = 3, solve y x³

A. -108
B. 108
C. 27
D. 4

Correct answer: B

Rationale: With y = 4 and x = 3, the expression is y × x³. Substituting the values, we get 4 × 3³ = 4 × 27 = 108. Therefore, the correct answer is 108. Option A (-108) is incorrect because the negative sign is not part of the result. Option C (27) is incorrect as it only represents x³ without considering the value of y. Option D (4) is incorrect as it represents the initial value of y, not the result of y × x³.

2. Calculate the product of (99)(0.56) =

A. 99.30
B. 99.56
C. 55.44
D. 199.54

Correct answer: C

Rationale: To find the product of 99 and 0.56, multiply the two numbers: 99 x 0.56 = 55.44. Therefore, the correct answer is 55.44.

3. Subtract 32 divided by 8\9.

A. 36
B. 32
C. 40
D. 44

Correct answer: A

Rationale: 32 ÷ (8\9) is the same as 32 × (9\8) = 36.

4. There are 225 pieces of candy in a large jar. Ben wants to give the 25 campers in his group an equal amount of candy. How many pieces of candy will each camper receive?

A. 9 pieces
B. 7 pieces
C. 8 pieces
D. 6 pieces

Correct answer: A

Rationale: To determine how many pieces of candy each camper will receive, divide the total number of pieces of candy (225) by the number of campers (25): 225 ÷ 25 = 9 pieces per camper. Therefore, each camper will receive 9 pieces of candy to ensure they all get an equal amount. Choice B, 7 pieces, is incorrect because the total number of candy pieces divided equally among 25 campers results in 9 pieces per camper, not 7. Choice C, 8 pieces, and choice D, 6 pieces, are also incorrect as they do not accurately reflect the division of 225 pieces of candy among 25 campers.

5. What is the result of multiplying 8 by 2?

A. 16
B. 22
C. 24
D. 32

Correct answer: A

Rationale: The correct answer is A: 16. When you multiply 8 by 2, the result is 16. Choice B (22), Choice C (24), and Choice D (32) are incorrect as they do not represent the correct multiplication of 8 by 2.
