Your cell phone plan costs 55 dollars a month, plus 35 cents per minute. Write an equation to represent the monthly bill of the cell phone plan.
F(x) = 55x + 0.35
F(x) = 55x + 15
F(x) = 0.35x + 55
F(x) = 35x + 55

Respuesta :

F(x)= (x number of minutes talked)*0.35 + (monthly charge of 55)
so F(x) = 0.35x + 55
F(x) = 0.35x+55
(0.35 × minutes in a month)×55
