Question

Mr. Wilson wants to park his car in his parking garage. To find the cost, he uses the equation D= 3H+6, where D represents the total amount, in dollars, charged for parking a car for H hours. If Mr. Wilson spent $30, how many hours did he park in the parking garage?

Answer 1

Answer:
`8\ hours`

Explanation:

You know that Mr. Wilson uses the following equation to find the cost:

`D= 3H+6`

Then, if Mr. Wilson spent $30, you can follow these steps in order to calculate how many hours he parked in the parking garage:

1. You need to substitute
`D=30` into the given equation:

`30= 3H+6`

2. Now, you must solve for "H":

`30= 3H+6\\\\30-6=3H\\\\24=3H\\\\(24)/(3)=H\\\\H=8`

Therefore, based on the result, you can conclude that Mr. Wilson parked his car in the parking garage for 8 hours.
