<s>[INST] A shopper has a coupon for 25% off the price of any single item purchased from a particular store. If she buys a shirt priced at $45.00 plus tax, and she presents the coupon at the time of checkout, she’ll get $11.25 (25% of $45.00) off the price.  Therefore, the discount is only applied to the original price of the item at the store’s checkout when the transaction is completed. If the store tax is 8%, what is the final amount she pays, and shouldn’t the shopper get 25% off of the taxed purchase?[/INST]
