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:

Chris rent the boat for a maximum of 13 hours

Step-by-step 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.

[tex]2h+4\le 30[/tex]

We can now solve this inequality for h hours.

[tex]2h\le 30-4[/tex]

[tex]2h\le26[/tex]

Divide both sides by 2

[tex]h\le13[/tex]
