A telephone plan cost $42 per month, Plus $0.08 per minute of calls made. Another plan costs $50 per month plus $0.05 per minute of calls made. Which system of equations could you use to compare the monthly cost of the plans?
A. c=42-0.08m
c = 50 - 0.05m
B. c = 42m + 0.08
c = 50m +0.05
C. c = 42 + 0.05m
c = 50 + 0.08m
D. c = 42 + 0.08m
c = 50 + 0.05m
They are asking for the monthly pay, so $42 per month, when it says per, you multiply it by m. it also says plus 0.08. same thing with the second plan.
