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 $80 for the truck and $50 per hour for the movers. Company B charges $60 for the truck and $55 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 = 80x + 50 y = 60x + 55 B. 50y = x + 80 55y = x + 60 C. 50y = 80x 55y = 60x D. y = 50x + 80 y = 55x + 60
