canoe service rents. they charge $20 rental fee plus $2.50 an hour. what is the maximum number of hours someone can rent a canoe and spend no more than $26.25

Question

how do i solve this? 

Answer 1

C=2.50h + 20 

where C is the total cost and h is the number of hours 

 

26.25=2.50h + 20

Subtract 20 from both sides 

 

6.25=2.50h 

Divide both sides by 2.50 

 

2.50=h 

 

Assuming you have to rent the canoe for whole hours, maximum number of hours a person can rent a canoe without spending more than $26.25 is 2 hours
