Question

A cable installer chargers $52.50 per hour plus a $75.00 service charge. your father's firm hires him to hook up his company's internet service. Find the total charges if it takes the cable installer 4.5 hours to complete the task

Answer 1

So the cable installer charges 52.50 an hour. meaning you would multiply that by whatever amount of hours he will work. so 52.50 times 4.5 hours equals $236.25. Now he also charges an extra fee for the service, So we add 75 dollars onto that making it $311.25.

If you want it in formula form here you go

y represent total amount in the end and x equals amount of hours

y=52.50x + 75

y = 52.50(4.5) + 75

y = 236.25 + 75

y = 311.25
