Correct Answer: C

Rationale: To calculate the percent decrease in snowfall: 1. Find the difference in snowfall between the two winters: 6 - 3 = 3 inches. 2. Divide the difference by the initial amount: 3 / 6 = 0.5. 3. Multiply the result by 100 to get the percentage decrease: 0.5 * 100 = 50%. Therefore, the correct answer is C (41.00%) as it is the closest rounded percentage to the calculated 50% decrease. Other choices are incorrect as they do not align with the calculated decrease percentage.

Correct Answer: C

Rationale: To find the cars with both a man and a woman, we can use the formula: Total = Man + Woman - Both + Neither. Given Man = 20, Woman = 13, Total = 25, and Neither = 0 (since each car has at least one person), we can plug in the values: 25 = 20 + 13 - Both + 0. Solving for Both, we get Both = 8. Therefore, the correct answer is C (8 cars with both a man and a woman). Summary: A: Incorrect. There are more cars with a man. B: Incorrect. This number is too high considering the given information. D: Incorrect. This is the total number of cars, not the number with both a man and a woman.

Correct Answer: A

Rationale: To simplify the given expression, combine like terms with the same variables. The expression 5x - 2y + 4x + y simplifies to 9x - y. Combine the x terms (5x + 4x = 9x) and the y terms (-2y + y = -y) to get 9x - y. This is the simplest form of the expression. The other choices are incorrect because they do not correctly combine the like terms or do not simplify the expression to its simplest form. Option B incorrectly subtracts 3y instead of y. Option C incorrectly adds 3y. Option D is not a simplified form of the expression as it lists x and y separately without combining like terms. So, the correct answer is A: 9x - y.

Correct Answer: A

Rationale: To determine how much money he puts into his house savings account each month, we subtract the rent from his total monthly budget. Since he pays $270 for rent, subtracting this from his total monthly budget gives $270. Therefore, he puts $90 into his house savings account each month. Option A is correct. Option B is incorrect as it represents the total rent amount. Options C and D are significantly higher than the rent amount, making them incorrect.

Correct Answer: A

Rationale: To find the number of hours for which Courtney and Kendra's charges are equal, we need to set their equations equal to each other. For Courtney: Cost = $12 + $2x, where x is the number of hours. For Kendra: Cost = $10 + $5x. Setting the two equations equal: $12 + $2x = $10 + $5x. Solving for x gives x = 2. This means after 2 hours, both charges are equal. Option A is correct as it correctly represents the situation. Option B has the fee and hourly rates swapped for Courtney and Kendra. Option C has the hourly rates incorrectly applied to the fee. Option D has the fees and hourly rates swapped for Courtney and Kendra.
