2a) Company A rents copy machines for $300 a month plus $0.05 per copy. Company B charges $600 a month plus $0.01 per copy. Which equation can be used to find the number of copies, c, both companies need in order to charge the same amount? * 0.05c+600 = 0.01c+ 300 0.05c-300 = 0.01 + 600 0.05c+300 = 0.01c + 600 0.05c+0.01c = 300+ 600
