Mary’s yard is a mess. She needs to hire someone to prune her trees and shrubs. A landscaping service she calls quotes her a price of $15 consultation fee plus $8 an hour for the actual work. Mary’s neighbor has offered to help her out. She doesn’t charge a consultation fee, but does charge $10 an hour for her work. Write two equations, one that describes the landscaping service charge and one that describes your neighbor’s charge. Let C equal the charge as a function of h, the number of hours worked.
The landscaping service charges a fixed $15 consultation fee plus $8 for each hour, so its equation is C = 15 + 8h. The neighbor charges $10 per hour and no fixed fee, so her equation is C = 10h. These match choice C.
