Question #164600
Solve using Polya’s four-step problem solving strategies.
1. A big department store is having a clearance sale, discounting all items by 40%. If the appliance you’re eyeing on is Php 1,500 after the markdown, how much did it cost before? How much will you save if you took advantage of this sale?
Expert's answer
If the appliance you’re eyeing on is Php 1,500 after the markdown, then it cost 1,500/(1 - 0.4) = 2500 before the sale. You will save 2500 - 1500 = 1000 if you took advantage of this sale.
