Correct Answer: C

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: B

Rationale: The correct answer is B: c = p/m. To calculate the cost of gas per mile, we need to divide the price of gas (p) by the car's average mileage (m) in miles per gallon. This gives us the cost of gas per mile. Rationale: 1. The formula for cost per mile is calculated by dividing the price of gas by the car's average mileage. 2. Choice A (c = dp/m) is incorrect because it multiplies the price of gas by distance before dividing by mileage, which is not the correct calculation for cost per mile. 3. Choice C (c = mp/d) is incorrect as it multiplies average mileage by price before dividing by distance, which is not the correct calculation for cost per mile. 4. Choice D (c = m/p) is incorrect as it divides mileage by price, which does not give the cost of gas per mile.

Correct Answer: D

Rationale: To determine the order from least to greatest, we need to evaluate each expression. First, calculate each expression: 2^-1 = 1/2 -(4/3) = -4/3 (-1)^3 = -1 (2/5) = 2/5 Now, compare the values: -4/3 is the smallest, followed by -1, then 2/5, and finally 1/2. Therefore, the correct order is -(4/3), (-1)^3, (2/5), 2^-1. Option D correctly lists the expressions in this order. Option A is incorrect because it has the wrong order of the expressions. Option B is incorrect as it has a different order compared to the correct one. Option C is incorrect as it also has a different order than the correct one.

Correct Answer: C

Rationale: To solve the equation 3x + 4 = 19, we first isolate the variable x. Subtract 4 from both sides: 3x = 15 Then, divide by 3 on both sides: x = 5 Therefore, the correct answer is C: x = 5. Choice A is incorrect as 3(3) + 4 = 13, not 19. Choice B is incorrect as 3(4) + 4 = 16, not 19. Choice D is incorrect as 3(6) + 4 = 22, not 19.

Correct Answer: C

Rationale: To find the number of hosts, we first need to determine the total number of parts in the ratio, which is 9 + 2 + 1 = 12 parts. Then, for hosts, we calculate (2/12) * 36 = 6 hosts. Therefore, the correct answer is C. Choice A (3) is incorrect because it does not properly reflect the ratio provided. Choice B (4) is incorrect as well because it does not align with the ratio. Choice D (8) is incorrect because it exceeds the total number of employees in the restaurant.
