Sandy is upgrading her internet service. Fast internet charges $60 for installation $50.45 per month. Quick internet has free installation but charges $57.95 per month write an equation that can be used to find the number of months for which the internet service would cost the same?

Respuesta :

Fast internet : 60 + 50.45m
Quick internet : 57.95m

to find the number of months they would be equal....set them equal to each other and solve for m, the number of months

60 + 50.45m = 57.95m
60 = 57.95m - 50.45m
60 = 7.50m
60/7.50 = m
8 = m.....so they will be the same at 8 months
