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. 45y = x + 100 60y = x + 90 B. y = 45x + 100 y = 60x + 90 C. 45y = 100x 60y = 90x D. y = 100x + 45 y = 90x + 60
