You rent a canoe for $5 per hour. your cost before the tax is added is $12.50. a) write and b) solve an equation to find the number of hours that you rented the canoe. 100 points : 3

2.5 hrs;t/c=h

Step-by-step explanation

The easiest way to do this is by setting up your units so that they cancel to give you what you want.  You are looking for hours, and you are given both a rate ($5/hour) and a final amount ($12.50).

($12.50) /  ($5/hour) = 2.5 hours

Now just convert 2.5 hours into actual time units, (2 hours, 30 minutes)

Let's write this into a variable equation.  Let's call t the "total cost" and c the "hourly cost" and h "hours rented."

t/c = h
