The fraction that Trinity must mark down all prices in her store so that the overall price decreases in both stores are the same is 3/8, 0.375, or 37.5%
A markdown is a price reduction strategy used by retailers to attract customers to their stores.
A markdown reduces the profit margin.
First day's price reduction = 25%
Reduced price after the first markdown = 75% (1 - 25%)
The second day's price reduction = 1/3 or 33.33%
Reduced price after the second markdown = 50% (75% x (1 - 33.33%)
First day's price reduction = 20%
Reduced price after the first markdown = 80% (1 - 20%)
Reduced price after the second markdown = 50% like Alexis' (80% x 50%/80%)
50%/80% = 62.5% or 0.625
Therefore, the second day's price reduction must be 3/8, 0.375, or 37.5% (1 - 0.625).
Thus, the fraction that Trinity must mark down all prices in her store so that the overall price decreases in both stores are the same is 3/8
