Clarence bought 5 rolls of color film and 4 rolls of black-and-white film for his camera for a total of $24.00. The black-and-white film costs $1.50 per roll more than the color film. How much does one roll of the black-and-white film cost?

x - price for roll of collor film x + 1.50 - price for black and white roll of film 5 x + 4 ( x + 1.50 ) = 24 5 x + 4 x + 6 = 24 9 x = 18 x = 2 [ t e x ] 2 + 1.50 = 3.50 [ / t e x ] One roll of the black and white film costs 3.50$
