Q: For the summer, the clothing store has a 50% discount for all items. On Wednesdays, there is an additional $10.00 off on all jeans after the summer discount is applied. Before the sales tax applies, the cost of a pair of jeans is $14.50. How much was the original cost for the jeans before all the discounts?
A:
Before the Wednesday discount, the cost of the jean is $14.50 + $10.00 = $24.50. Since the original price was reduced by 50%, the original cost for the jeans is $24.50 * 2 = $49.00. The answer is 49.
