A shirt originally cost $38.30, but it is on sale for $34.47.What is the percentage decrease of the price of the shirt ? If necessary, round to the nearest percent

The answer to your question is 10%

Step-by-step explanation:

Data

Original cost = $38.30

Price after discount = $34.47

Percent of decrease = ?

Process

1.- To solve this problem use proportions and cross multiplication. The original cost will be 100%.

                  38.3 % 100%

                   34.47%  x

                   x = (34.47 x 100)/38.3

                   x = 3447/38.3

                   = 90 %

2.- Calculate the percentage of decrease

    Result = 100 - 90

               = 10%
