Answer:
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%
