Sam is shopping for a new pairs of shoes. On Monday the shoes were on sale for %40.00, but because they became popular, by Saturday the price had risen to $44.00. What is the percent of increase on the price from Monday to Saturday

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.
