Question

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

Answer 1

Answer: The garbage charges $\ \ \frac{7}{3}$ per hour

The equation shows the relation is $c=\frac{7}{3}p$  

Step-by-step explanation:

Given: Alexandra paid $7 to park her car for 3 hours at the parking garage.

⇒ Cost for 3 hours parking=$7

To find cost of parking for 1 hour, divide cost for 3 hours by $7

⇒Cost for 1 hour  =$\ \ \frac{7}{3}\text{per hour}$

Therefore, the garbage charges $\ \ \frac{7}{3}$ per hour

For c is the cost in dollars of parking and p is the number of hours, the equation shows the relation is as follows:-

$c=\frac{7}{3}\times\ p$

$c=\frac{7}{3}p$  

Answer 2

$7 was paid to park the car for 3 hours.

3 hours  cost $7 to park

1 hour  =   $ (7/3)

So every 1 hour cost $(7/3)

Therefore cost in dollars,  c  =  (7/3)*p

Therefore c = (7/3)p,    where c is the cost in dollars of parking and p is the number of hours.
