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

• C +1,200 = 85h

When y = 10 what does z equal if z = 2y - 6?

Aiden, Avery, and Anika are building a robot for their school project. They need to hire an electrician to wire their robot. The electrician charges $150 per hour and also requires $800 for the wire. Can you help them figure out the total cost, C, if the electrician takes h hours to finish the wiring?

• C = 150h + 800

• C+800 = 150h

• C = (150+800)h

• C + 800 = 150h
