If you make 25 minutes o long distance calls per month,what will it cost? write an equation

Question

Metro PCS charges a flat monthly fee for $22.00 for a telephone line and $0.20 per minute for long distance calls.

Answer 1

Let x = the number of minutes

Let y - the total cost

y = mx + b

Y = .20m + 22

y = .20(25) + 22

y = 5 + 22

y = $27.00
