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

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.
