Let 
be the price of the merchandise before discount and tax are figured in.
A 25% discount means that the price Wally pays is 
of the retail price. This can be written as 
.
A 6.45% sales tax means that 
of that discounted price is being paid.
We can combine the discount and sales rate as 
.
As the maximum purchase price after discount and tax is $500, we set up the following equation:
Wally can purchase up to $626.27 in merchandise.

Carolyn won a $450 gift card, and she wants to spend it at the store where she works. Normally, she gets a 10% employee discount, but in one week, her store will be having an "Employee Appreciation Day" during which a 25% employee discount will apply. If, as an employee, she does not have to pay sales tax, how much more worth of merchandise (in terms of price before discount) will she be able to purchase by holding out to that day (nearest cent, if applicable)?
