  • cost of tiles=288*80=$230.40
    you paid 200 bucks
    .You will get nothing back but you have to pay more 30.40 bucks
  • a) A mark dwon greater than 99% and less than 100%

    Mark down 99.1% of x

    Original price: x

    Final price: original price -  mark down = x - 0.991 x = 0.009x

    => If orginal price is 1000 and mark down is 99.1% , final price = 0.009*1000 = 9

    You can check that the mark down is 99.1% of 1000 = 991.

    b) A mark down that is less than 1%

    Mark down: 0.1%

    Original price: 10,000

    Mark down: 10,000 * 0.1% = 10

    Final price: 10,000 - 10 = 9,990

    c) A mark up that is more than 200%

    Mark up: 300%

    Original price: 100

    => final price = 100 + 100*300% = 100 + 300 = 400
