Evelyn, Mason, and Isla are planning a DIY project to wire their treehouse. They found an electrician who charges $85 per hour and the wire needed for the job costs $1,200. Can you help them figure out the total cost, C, of the wiring job if it takes the electrician h hours to finish?

• C = (85+1,200)h

• C+85h = 1,200

• C = 85h + 1,200
