If you would like to know how much does each charge per hour, you can calculate this using the following steps:
x ... the number of hours
a plumber: y = 55x + 85 = 55 * 1 + 85 = 55 + 85 = $140 per hour
an electrician: y = $115 per hour
The correct result would be: the plumber charges $140 per hour and the electrician charges <span>$115 per hour.</span>
