In the second week of the sale, the prices are reduced buy 25% of the previous week's price. In the third week of the sale, ther prices are again reduced by 25% of the previous week's price. In the fourth wee of the sale, the prices are reduced by 25% of teh previous week's price. Julie thinks this will bmean that the price wil be reduced to $0 after the four reductions because 4 x 25% = 100%.
Explain why Julie is wrong.
