The budget for a school band was $8,000 in 2010. The budget decreased by 15% from 2010 to 2011 and then increased by 22% from 2011 to 2012. Which of the following expressions represents the budget, in dollars, for the school band in 2012?
- (1.15)(1.22)(8,000)
- (0.85)(1.22)(8,000)
- (1.15)(0.78)(8,000)
- (0.85)(0.78)(8,000)
The correct answer is: (0.85)(1.22)(8,000)
Actual budget in 2010 = 8000
The budget decreased by 15% from 2010 to 2011,
Budget in 2011 = 
= (0.85) 
8000
The budget is increased 22% from 2011 to 2012
Budget in 2012 = 
= (0.85) (1.22) (8000).
