1. Mr. De Mesa put up a business that offers computer repair which he charges a base of P 350.00 for each visit and an additional of P 20.00 per hour for his labor, given by the function C(r) 350 + 20r. He also has rentals at his shop with a base of P 15.00 for the first hour and an additional of P 8.00 per thirty minutes defined by the function S(r) = 15 + 8r. Determine the C(r) +S(r).
