You can put this solution on YOUR website! There are two cell phone companies that offer different packages.
Company A charges a monthly service fee of $31 plus $0.07/min talk-time.
Company B charges a monthly service fee of $42 plus $0.06/min talk-time.
The model for Company A can be written as A = 31 + .07 * x
The model for Company B can be written as B = 42 + .06 * x
x represents the number of minutes used each month.
If the average number of minutes used each month is 1,172, how much does this cost for each Company?
company A would charge 31 + .07 * 1172 = 113.04
company B would charge 42 + .06 * 1172 = 112.32
