What is asked in the problem?
What is the rate of decrease?


Given:
Electricity cost of a business decreased from $12,000 to $10,920.


Find the decrease of cost
$12,000 - $10,920 = $1, 080


$1,080 is what percent of $12,000
1,080 = 12,000x

%281080%2F12000%29+=+%2812000x%2F12000%29

0.09 = x
or
9%
