A contactor is making preparations to re-tile the border around a swimming pool. The pool measures 60 feet by 30 feet. The border extends 1 foot from each side of the edge of the pool. The contractor is going to use that are 0.25 feet squared. A case of tiles contains 50 tiles and costs $15.00, but there`s a 10% discount on orders of 5 or more cases.
If the contractor must buy a full cases of tiles, what will it cost to purchase tiles for the border of the pool?

  • math - ,

    area of pool+border = 62*32 = 1984
    area of pool alone = 60*30 = 1800
    area of border = 184 ft^2

    tiles per ft^2 = 4
    tiles for border = 184*4 = 736

    cases needed = 736/50 = 14.72, or 15

    normal cost of 15 cases = 15*15 = $225
    after 10% discount of $22.50: $202.50
