Question

"Jason receives $15.00 per week for lunch in school. The cafeteria charges $2.20 for a plate lunch. Write an equation that will determine the amount of money, m, the student will have left after d days. Assume that the student purchases only the plate lunch each day."

a) m = 15 - 2.20d
b) m = 2.20d - 15
c) m = 15d - 2.20
d) m = 2.20 - 15d

Answer 1

The equation that will determine the amount of money the student will have left after d days is m = 15 - 2.20d.

Step-by-step explanation:

The equation that will determine the amount of money the student will have left after d days is m = 15 - 2.20d. This equation represents the student's initial amount of money ($15.00) minus the cost of the plate lunch ($2.20) multiplied by the number of days (d) that the student has been purchasing the plate lunch.
