A food truck sells salads for 2.00 each. The food truck's revenue from selling a total of 209 salads

Q: What is the correct answer for SAT Maths?

The correct answer is D. Let s be the number of salads sold and d be the number of drinks sold. We have two equations: 1) s + d = 209 (total items sold) and 2) 6.50s + 2.00d = 836.50 (total revenue). From equation (1), d = 209 - s. Substitute this into equation (2): 6.50s + 2.00(209 - s) = 836.50. Distribute: 6.50s + 418 - 2.00s = 836.50. Combine like terms: 4.50s + 418 = 836.50. Subtract 418 from both sides: 4.50s = 418.

Q: A food truck sells salads for 2.00 each. The food truck's revenue from selling a total of 209 salads and drinks in one day was $836.50. How many salads were sold that day?

The correct answer is D. Let s be the number of salads sold and d be the number of drinks sold. We have two equations: 1) s + d = 209 (total items sold) and 2) 6.50s + 2.00d = 836.50 (total revenue). From equation (1), d = 209 - s. Substitute this into equation (2): 6.50s + 2.00(209 - s) = 836.50. Distribute: 6.50s + 418 - 2.00s = 836.50. Combine like terms: 4.50s + 418 = 836.50. Subtract 418 from both sides: 4.50s = 418.

Let s be the number of salads sold and d be the number of drinks sold. We have two equations: 1) s + d = 209 (total items sold) and 2) 6.50s + 2.00d = 836.50 (total revenue). From equation (1), d = 209 - s. Substitute this into equation (2): 6.50s + 2.00(209 - s) = 836.50. Distribute: 6.50s + 418 - 2.00s = 836.50. Combine like terms: 4.50s + 418 = 836.50. Subtract 418 from both sides: 4.50s = 418.50. Divide by 4.50: s = 418.50 / 4.50 = 93. So, 93 salads were sold. Wait, the provided answer is D (105). Let me recheck. 6.50s + 2(209-s) = 836.50 => 6.5s + 418 - 2s = 836.50 => 4.5s = 836.50 - 418 => 4.5s = 418.50. s = 418.50 / 4.5 = 93. My calculation is correct for 93. If the answer is 105, then 6.5(105) + 2(209-105) = 682.5 + 2(104) = 682.5 + 208 = 890.5, which is not 836.50. Let's re-examine the question. No, it's a standard system of equations. The provided answer key for C19 is B (93). My calculation is correct. So, the explanation for B is correct. I will use 93 as the correct answer and B as the option.
