Alexandra paid $7 to park her car for 3 hours at the parking garage. The garage charges an hourly parking rate.
SCORPION-xisa [38]

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
