A plumber charges $25 for a service call plus $50 per hour of service. Write an equation in slope-intercept form for the cost, C, after h hours of service. 

• C = 25 + 50h
• C = 50 + 25h
• H = 25 + 50c
• H = 50 + 25c

Talk time Phone Company charges $0.12 per minute of phone use plus a monthly service fee of $8.00 for its phone service.  Which equation below can be used to find c, the total cost for one month when m, minutes are used?

• c = 0.12m + 8m
• c = 8m + 0.12m
• c = 0.12m + 8
• c = 0.20m
