It has a flat rate of $14. Plus it costs an additional $3 per hour. So the first thing we need to do is subtract 14 from 32. This way we can see how much she paid in the hourly charges. 32-14 = 18. Now that we know that she paid $18 in hourly charges, we need to divide that by 3. 18/3 = 6. So she rented the bike for 6 hours.
