Correct Answer: D

Rationale: To calculate Matt's new wage, we need to add the 3/20 increase to his original wage w. So, the new wage is w + 3/20w = 23/20w = 1.15w, which corresponds to choice D. Choice A is incorrect as it represents a decrease. Choice B is incorrect as it represents a smaller increase. Choice C is incorrect as it represents a larger increase than what Matt received.

Correct Answer: C

Rationale: To calculate Annie's total bill: 1. Cost of shirts: 5 shirts x $3 = $15 2. Cost of pants: 4 pants x $6 = $24 3. Cost of mending: 2 items x $5 = $10 4. Subtotal = $15 + $24 + $10 = $49 5. Add 8% sales tax: $49 x 0.08 = $3.92 6. Total bill = $49 + $3.92 = $52.92 Therefore, the correct answer is C ($52.92). The other choices are incorrect because they do not accurately factor in the cost of mending and sales tax. Option A, B, and D do not consider the additional charges for mending and tax, leading to incorrect totals.

Correct Answer: D

Rationale: The total bill includes the original cost of dinner and the tip. To find the tip amount, we calculate 20% of $48.30, which is $9.66. Adding this to the original bill gives $48.30 + $9.66 = $57.96. Therefore, the correct answer is D. Option A is incorrect as it only represents the tip amount. Option B is incorrect as it is the original bill amount without the tip. Option C is incorrect as it is the same as the original bill without the tip.

Correct Answer: B

Rationale: To simplify the expression, we follow the order of operations (PEMDAS). First, we calculate the exponents: 52(3) + 3(-2)^2 / 4 + 9 - 2(5-8) = 156 + 3(4) / 4 + 9 - 2(3) = 156 + 12 / 4 + 9 - 6. Then, we perform division and multiplication from left to right: 156 + 3 + 9 - 6 = 168. Therefore, the correct answer is 87/19. Choices A, C, and D are incorrect as they do not correctly simplify the expression following the order of operations.

Correct Answer: C

Rationale: To determine the correct order from least to greatest, convert all fractions to decimals: - (1/7) = 0.142857 - 0.125 - (6/9) = 0.666666 - 0.60 The correct order is 0.125, (1/7), 0.60, (6/9) because 0.125 is the smallest, followed by (1/7), then 0.60, and finally (6/9) which is equivalent to 0.666666. Other choices are incorrect because they do not follow the increasing order of magnitude. Choice A has the fractions in a different order, choice B has 0.60 in the wrong position, and choice D has the fractions in the wrong order. Therefore, choice C is the correct answer.
