Acellphone service provider charges $5.00 per month and $0.20 per minute per call. if a customer's current bill is $55, how many minutes did the customer use? (round any intermediate calculations and your final answer to the nearest whole minute.)

We can create the following linear equation.

y=0.2x+5

"x" will represent the call time and "y" will represent the monthly bill.

So when y (monthly bill) is 55...

55=0.2x+5

0.2x=50

x=250 minutes

250 minutes

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
