Solve the following application.
Business and finance. The electricity costs of a business decreased from $12,000 one year to $10,920 the next. What is the rate of decrease?

To find the rate of increase or decrease, divide the amount of increase
or decrease by the OLD amount.
The decrease was $1080. The old amount was $12,000 so
1080 ÷ 12000 = .09 = 9% decrease
