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 $100 for the truck and $50 per hour for the movers. Company B charges $90 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 = 100x + 50 y = 90x + 60 B. 50y = 100x 60y = 90x C. y = 50x + 100 y = 60x + 90 D. 50y = x + 100 60y = x + 90
