Mr. Caiden wants to do repairs to his house and requires 300 feet of metal roofing to do this. If each foot of roofing costs $8, and the supplier of the metal roofing brings in 250 feet of metal roofing for free, how much money is Mr. Caiden required to pay for the remaining metal roofing?
assistant
How many feet of metal roofing did the supplier bring in? ** The supplier brought 300 ft - 250 ft = <<300-250=50>>50 fewer feet of metal roofing.
How much money does Mr. Caiden have to pay for the remaining metal roofings? ** Therefore the total amount of money Mr. Caiden has to pay for the remaining metal roofings is 50 feet * $8/foot = $<<50*8=400>>400
