Question

Alexandra paid $7 to park her car for 3 hours at the parking garage. The garage charges a constant hourly parking rate.

Write an equation that shows the relationship between p, the number of hours parked, and c, the cost in dollars.

a) c = 7p
b) c = p/7
c) c = 3p
d) c = 7p + 3

Answer 1

The equation that shows the relationship between the number of hours parked and the cost in dollars is c = 7p. In this equation, c represents the cost in dollars and p represents the number of hours parked.

Step-by-step explanation:

The equation that shows the relationship between the number of hours parked and the cost in dollars is c = 7p. In this equation, c represents the cost in dollars and p represents the number of hours parked. Since Alexandra paid $7 to park her car for 3 hours, we can substitute p as 3 in the equation to find the cost: c = 7(3) = $21. Therefore, the equation c = 7p accurately represents the relationship between the number of hours parked and the cost in dollars.
