Answer:
$25.
Step-by-step explanation:
Let x be the original price of shorts.
We have been given that a store is having a sale in which all items are reduced 20%. The sales tax is 5%.
The price of shorts after 20% off will be:
Since tax is added after the discount, so the price of shorts after including the tax will be:
We are told that including tax, Jennifer paid $21 for a pair of shorts. So we can set an equation as:
Now let us solve for x.
Therefore, the original price of shorts was $25.
