Real World Linear Functions Review

Bandit is mowing lawns for a summer job. For every mowing job, he charges an initial fee of $15 plus a constant fee for each hour of work. His fee for a 5-hour job is $65.

Let y represent Bandit's fee (in dollars) for a single job that took x hours for him to complete.

Create an equation for the relationship between the fee and number of hours.
