Suppose sprint charged $50 per month plus 15 cents per minute while Verizon charges no monthly fee but 25 cents per minute. After how many minutes would the monthly bills be the same?

Respuesta :

At 50 minutes, the monthly bills will be same.

Step-by-step explanation:

Sprint charges;

Per month fee = $50 = 50*100 = 500 cents

Charges per minute = 15 cents

Let,

x be the minutes.

S(x) = 500 + 15x

Verizon charges;

Per minute charges = 25 cents

V(x) = 25x

When the bills will be same, the functions will be equal.

S(x) = V(X)

[tex]500+15x=25x\\500=25x-15x\\500=10x\\10x=500\\[/tex]

Dividing both sides by 10

[tex]\frac{10x}{10}=\frac{500}{10}\\x=50[/tex]

At 50 minutes, the monthly bills will be same.
