Your computer store is having an incredible sale. The price on one model is reduced by 40%. Then the sale price is reduced by another 40%. If x is the computer’s original price, the sale price can be modeled by ( x − 0.4 x ) − 0.4 ( x − 0.4 x ) . a. Factor out ( x − 0.4 x ) from each term. Then simplify the resulting expression. b. Use the simplified expression from part (a) to answer these questions. With a 40% reduction followed by a 40% reduction, is the computer selling at 20% of its original price? If not, at what percentage of the original price is it selling?
