Solve the problem.Sybil is having her yard landscaped. She obtained an estimate from two landscaping companies. Company A gave an estimate of $180 for materials and equipment rental plus $60 per hour for labor. Company B gave an estimate of $230 for materials and equipment rental plus $50 per hour for labor. We can represent this situation with the system of linear equationsc = 180 + 60xCompany Ac = 230 + 50xCompany Bwhere c is the total cost and x is the number of hours of labor. Graph the system. What is the x-coordinate of the intersection point of the graphs? Describe what this x-coordinate means in practical terms.
A. 5; for 5 hours of labor, both companies charge the same. B. 8; for 8 hours of labor, both companies charge the same. C. 4; for 4 hours of labor, both companies charge the same. D. 4; there is a number of hours of labor, for which both companies charge $400.
