I want to rent a bike in a store that charges me $15 when I take the bike out and x dollars per hour of biking. I can only spend $40 for the ride.
What is the maximum charge per hour I can take if I want to ride by 8 hours?
The inequality uses x as a variable. Solving this inequality
8x + 15 < 40
Will give the maximum charge per hour that I could take to have my 8-hour ride.
The answer is $3.125 per hour. Not bad
