    10%

    Step-by-step explanation:

    In order to find the percent of incrase, find out the difference in the 2 prices

    first price = $40

    second price=$44

    therefore, difference = 44-40 = $4

    next is to Divide the original price by the difference of the two prices

    Percent = difference/original

    4/40=0.1 (multiplying it by 100%)

    0.1 x 100% = 10%

    the percent of increase on the price from Monday to Saturday is 10%

    The price was increased in 10% from monday to saturday.

    Step-by-step explanation:

    The original price of the shoes was $40.00 and the new price is $44.00, so the increase in price can be calculated by subtracting the new price by the old one:

    increase = new price - old price = 44 - 40 = 4

    In order to know wich percentage $ 4 represents in relation to the original price of the shoes, $40, we can apply a rule of three in such a way that $40 is to 100% such as 4% is to "x" %. So we have:

    40 - > 100%

    4 - > x%

    40/4 = 100/x

    40*x = 4*100

    x = 400/40 = 10%

    The price was increased in 10% from monday to saturday.
