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: C

Rationale: To find the total potential savings, we first calculate the 20% discount on the car price: 20% of $26,580 = $5,316. Next, we calculate the total monthly payments saved: 3 payments x $250 = $750. Adding the discount and saved payments gives us a total potential savings of $5,316 + $750 = $6,066. Therefore, choice C is correct. Choice A is incorrect because it does not account for the monthly payments saved. Choice B is incorrect as it only considers the discount on the car price, ignoring the saved payments. Choice D is incorrect as it overestimates the savings by combining the discount and payments saved twice.

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: B

Correct Answer: D

Rationale: To solve the equation 8x - 6 = 3x + 24, first, simplify both sides. Subtract 3x from both sides to get 5x - 6 = 24. Then, add 6 to both sides to get 5x = 30. Finally, divide by 5 to find x = 6. This is the correct solution as it satisfies the original equation. Choice A, B, and C are incorrect as they do not result in a true statement when substituted back into the equation.
