Question 313542: The equation C=mx+b can be used to model the monthly cost, C, of a cell phone plan where b is the flat monthly cost, m represents the cost in dollars per minute and x is the number of minutes used in the month. Choose a flat monthly rate and cost per minute and insert the values you have chosen for m and b into the equation. Then use this equation to find the total monthly cost, C, if 73 minutes are used.

C=mx+b
Let cost per minutes = .30
Let the flat rate = $15
Substitute the numbers for variables: c=.30x+15
.
Let x=73
So, c=.30(73)+15
Cost = $36.90
