You can put this solution on YOUR website! The cost, C, in hundreds of dollars, of a commercial telephone line for a business is given by C = 0.75m + 3, where m is the number of months that the telephone line has been in use. Find the cost of the phone line for 1 month, 2 months, 3 months, and 8 months.
-------------------------
C(m) = 0.75m + 3
C(1) = 0.75(1)+3 = 3.75
C(2) = 0.75(2)+3 = 4.50
C(3) = 0.75(3)+3 = 5.25
C(8) = 0.75(8)+3 = 9.00
