Solve the problem.A couple have bought a new house and are comparing quotes from two moving companies for moving their furniture. Company A charges $120 for the truck and $45 per hour for the movers. Company B charges $100 for the truck and $60 per hour for the movers. Create a cost equation for each company where y is the total cost and x is the number of hours of labor. Write a system of equations.

A. y = 45x + 120 y = 60x + 100 B. 45y = 120x   60y = 100x C. y = 120x + 45 y = 100x + 60 D. 45y = x + 120  60y = x + 100
