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