Correct Answer: B

Rationale

Choice B is correct. It’s given that $2 point 5 0 x, plus 7 point 0 0 y$ is equal to the total amount of money, in dollars, a food truck charges for x drinks and y salads. Since each salad has the same price, it follows that the total charge for y salads is $7 point 0 0 y$ dollars. When $y equals 1$ , the value of the expression $7 point 0 0 y$ is $7 point 0 0 times 1$ , or 7.00. Therefore, the price for one salad is 7.00 dollars.

Choice A is incorrect. Since each drink has the same price, it follows that the total charge for x drinks is $2 point 5 0 x$ dollars. Therefore, the price, in dollars, for one drink is 2.50, not 7.00. Choices C and D are incorrect. In the given equation, F represents the total charge, in dollars, when x drinks and y salads are bought at the food truck. No information is provided about the number of drinks or the number of salads that are bought during the day. Therefore, 7.00 doesn’t represent either of these quantities.
