In the equation above, F represents the total amount of money, in dollars, a food truck charges for x drinks and y salads. The price, in dollars, of each drink is the same, and the price, in dollars, of each salad is the same. Which of the following is the best interpretation for the number 7.00 in this context?
A
The price, in dollars, of one drink
B
The price, in dollars, of one salad
C
The number of drinks bought during the day
D
The number of salads bought during the day
Correct answer: B
Explanation
Choice B is correct. It’s given that 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 dollars. When , the value of the expression is , 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 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.
