    Heh guys, any clue to how to set up those problems


    The ridees of a rectangle are 15 inches by 8 inches. If the rectangle were changed into a square of equal area, what would be the approx. lenght of each sifde of the sqare?

    1. 6.33
    2. 8.00
    2. 10.96
    3. 11.50
    4. 11.50
    5. 15.50



    The current sales price of a power drill is $117. This is $ 30.00 more than half the list price. At what discount is the drill being sold?

    1. 32.8%
    2. 48.7
    3. 25.6
    4 74.4
    5. 67.2

    1)
    15X8 = 120 sqaure inches.....a square has 4 equal sides and the area is the product of two sides... you know that 11x11 is 121, so each side is slightly less than 11, or 10.96


    2)
    117 = 30 + 1/2(x)
    87 = 1/2(x)
    X = 174... the original cost of the drill
    174(.328) = 57... 174-57 = 117

    117 = 30 + 1/2L
    L (list price) = 174

    The difference between the list price and sale price is: 174-117 = 57

    So, the % dicount = price difference/list price: 57/174 = 32.8% [A]
