A shipper bought three of the same shirt and paid $63 after the 30% discount. What was the original price of one of the shirts?

  • math - ,

    let x represent one of the shirts and then set up the equation

    3x-(3x*.3)=63

    because there are 3 shirts and after you find the total of the shirts you would usually subtract the percentage of that total from the total. The equation equals 63 from what was given. then solve

    3x-(3x*.3)=63
    3x-(.9x)=63
    2.1x=63
    x=30

    One shirt was $30

  • math - ,

    0.7x = 63

    x = 63/0.7

    x = 90

    90 / 3 = ?
