You are wallpapering two walls of a room. One wall measures 15 ft by 12 ft and the other measures 9 ft by 12 ft. The wall paper costs $19.40 per roll, and each roll covers 50 square feet. What does it cost to cover the two walls?

Wall #1 : 15x12 = 180
wall #2 : 9x12 = 108
total area = 288
number of rolls = 288/50 = 5.76
So you will have to buy 6 rolls
Cost = 6(19.50) = $117
