Question
Company Wages Pederson Electric charges $\$ 25$ per service call plus $\$ 18$ per hour for repair work. How long did an electrician work if the charge was less than $\$ 100 ?$ Assume the electrician rounds the time to the nearest quarter hour.
Step 1
Let $x$ represent the number of hours the electrician worked. The total charge for the service call and the repair work is $25 + 18x$. Since the total charge is less than $100, we have the inequality: \[25 + 18x < 100\] Show more…
