Wally has a $ 500 gift card that he want to spend at the store where he works. He get 25% employee discount , and the sales tax rate is 6.45% how much can wally spend before the discount and tax using only his gift card?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
