Naomi went shopping for a new pair of sneakers because of a sale. The store was offering a 10% discount. What number should she multiply the prices on the tags by to find the price she would have to pay, before tax, in one step?

Answer 1

To find the price Naomi would have to pay after a 10% discount, she should multiply the prices on the tags by \(0.90\).

This is because a 10% discount means she will pay 90% of the original price. Therefore, the calculation is:

\[ 1 - 0.10 = 0.90 \]

So, by multiplying the original price by \(0.90\), she will get the final price she has to pay before tax.
