Answer 2

The answer to your question is 10%

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%
