Question 1 of 5

A dry cleaner charges $3 per shirt, $6 per pair of pants, and an extra $5 per item for mending. Annie drops off 5 shirts and 4 pairs of pants, 2 of which need mending. Assuming the cleaner charges an 8% sales tax, what will be the amount of Annie's total bill?

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.

Question 2 of 5

Which of the following is the y-intercept of the line whose equation is 7y − 42x + 7 = 0?

Correct Answer: C

Rationale: To find the y-intercept, set x=0 in the equation 7y - 42x + 7 = 0: 7y - 42(0) + 7 = 0 7y + 7 = 0 7y = -7 y = -1 Thus, the y-intercept is (0, -1). Summary: A: Incorrect - The x-coordinate is not 1/6. B: Incorrect - The x-coordinate is not 6. C: Correct - The y-intercept is (0, -1). D: Incorrect - The x-coordinate is not -1.

Question 3 of 5

Which statement about the following set is true? {60, 5, 18, 20, 37, 37, 11, 90, 72}

Correct Answer: D

Rationale: The correct answer is D: The median is less than the mean. To find the median, first arrange the set in ascending order {5, 11, 18, 20, 37, 37, 60, 72, 90}. The median is the middle value, which is 37 here. To find the mean, add up all numbers and divide by the total count (sum/9). The mean is (60+5+18+20+37+37+11+90+72)/9 = 41.67. Since 37 (median) is less than 41.67 (mean), the statement is true. Other choices are incorrect because A is false as median ≠ mean, B is false since mean > mode, and C is false since mode ≠ median.

Question 4 of 5

A dry cleaner charges $3 per shirt, $6 per pair of pants, and an extra $5 per item for mending. Annie drops off 5 shirts and 4 pairs of pants, 2 of which need mending. Assuming the cleaner charges an 8% sales tax, what will be the amount of Annie's total bill?

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.

Question 5 of 5

What is the result of (4.71 10^3) - (2.98 10^2)? Which of the following is the correct simplified expression?

Correct Answer: D

Rationale: To subtract numbers in scientific notation, we need to ensure the exponents are the same. First, convert 2.98 x 10^2 to 0.298 x 10^3. Then, subtract 4.71 x 10^3 - 0.298 x 10^3 = 4.412 x 10^3. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not reflect the correct result of the subtraction operation.
