Question

Chris uses the equation C = 2 h + 4 to find the total cost, C, in dollars, of renting a boat for h hours. If Chris does not spend more than $30, what is the maximum number of hours she can rent the boat?

Answer 1

Chris rent the boat for a maximum of 13 hours

Explanation:

Chris uses the equation C=2h+4 to find the total cost C dollars of renting a boat for h hours.

If Chris does not spend more than $30, then he spend less or equal to $30.

`2h+4\le 30`

We can now solve this inequality for h hours.

`2h\le 30-4`

`2h\le26`

Divide both sides by 2

`h\le13`
