Solve and show your work:
During a week-long sale, a store reduced its prices on sale items by 10% each day.
A coat that was priced $80 on the first day of the sale was sold on the fourth day.
At what price was the coat sold?
Comments
80 * 0.9^3 = 58.32
Day 1: 80
Day 2: 80 * 0.9 = 72
Day 3: 80 * 0.9^2 = 64.8
Day 4: 80 * 0.9^3 = 58.32
100 ...90 ....81 ...72.9
72.9 /100 X 80 = 58.32 $ ANSWER
