A store set the price it sold a pair of jeans for by tripling the amount it had paid for the jeans. After a month, the jeans were marked down by $5. Two weeks later, the price was divided in half. Finally, the price was reduced $3, down to $14.99. How much did the store pay for the jeans?

Let the price the store paid for the jeans be P

Since the price was tripled, then itw's set at: 3P

Since itw's reduced by $5, then it went down to 3P - 5

Since itw's again reduced to half, then it went down to %283P+-+5%29%2F2

Since itw's finally reduced by $3, down to $14.99, then we can say that: %28%283P+-+5%29%2F2%29+-+3+=+14.99

3P - 5 - 6 = 29.98 ------ Multiplying by LCD, 2

3P - 11 = 29.98

3P = 40.98

P, or original price of jeans = 40.98%2F3, or $highlight_green%2813.66%29

You should be able to do your own check!!
