If you rent a canoe for 3 hours, you will pay $45. the hourly rate for renting a canoe is $10 per hour. write?

if the hourly rate is $10 then after 3 hours it will be $30, therefore you know there is an initial flat-rate fee of $15 in addition to the rental cost. The equation will therefore be C = 10h + 15 (C = cost, h = hours)
