Question

By careful reorganization, a company was able to reduce the cost of operation from $21,840 per month to $17,190 per month. By what percent was the cost of operation reduced?

Answer 1

Subtract the 17190 from the 21840. you get 4650. 4650 divided by 21840 is 0.21. The percent decrease is 21%

Answer 2

Answer: The cost of operation was reduced by 21.29%.

Explanation:

Since we have given that

Cost of operation earlier = $21,840 per month

Cost of operation now = $17,190 per month

Difference between them is given by

$21,840 - $17,190

=$4,650

Percentage by which the cost of operation was reduced is given by

`(4650)/(21840)* 100\\\\=21.29\%`

Hence, the cost of operation was reduced by 21.29%.
