A cable installer charges $40. an hour plus a $50.00 service charge. Figure the function c(h) = ?
Hitman42 [59]

Answer:

c(h) = 40*h + 50

Step-by-step explanation:

As the cable operator charges $40.00 for an hour so for h hours, the expression will be 40*h

And  

Lastly, he has to charge $50.00 must as service charge,

As the number of hours is variable here so the function will be in terms of hours.

So the resulting function will be:

c(h) = 40*h + 50
