Solve.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 $50 per hour for the movers. Company B charges $110 for the truck and $65 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. 50y = 120x 65y = 110x B. 50y = x + 120 65y = x + 110 C. y = 120x + 50 y = 110x + 65 D. y = 50x + 120 y = 65x + 110
