A cable company charges $75 for installation plus $20 per month. Another cable company offers free installation but charges $35 per month. For how many months of cable service would the total cost from either company be the same?
(a) 5
(b) 7
(c) 2
(d) 3

Respuesta :

it would be 5 months because if you do 75 + 20x = 35x
15x = 75
----- ------
15 15
x = 5
Your answer would be (A) :)
