Kalesha is purchasing a laptop. the original price of the laptop is $900. the store is offering 10% off on all computers. kalesha has a $100 gift card. how should kalesha determine the amount she will pay for her computer?

Take 10% of her laptop then subtract 100 from that

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.
