You know that the computer technician has a flat 65 dollar service charge. This will be added to the hours worked.
hours= h
40 dollars per hour. So, every hour worked is worth 40 dollars.
c(h)= 40h+65
If you input the number of hours he worked as h, you would have the total amount of money he made if you solved the expression.
I hope this helps!
