Respuesta :

the answer is C

 you would need to calculate X ( number of hours minus the first hour so x-1)

then multiply that by the rate of $5, then add the $7 for the first hour

The answer is C.

First hour = $7
Additional hour after the first = (x - 1) because the first hour is $7.

C(x) = $5(x-1) + $7

Hope this helps.
