Question 503655: 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?

You can put this solution on YOUR website!
p = price = amount customers pay
c = cost = amount the store paid for the jeans
p = 3c
.
After a month
sales price = p-5
.
After two weeks
sales price = (p-5)/2
.
Finally
sales price = (p-5)/2 -3
sales price = 14.99
.
(p-5)/2 -3 = 14.99
.
(p-5)/2 = 17.99
.
p-5 = 35.98
p = 40.98
.
p = 3c
3c = 40.98
c = 40.98/3
c = 13.66
.
The store paid $13.66 for the jeans.
.
Done.
