Fwam has a loyalty card good for a 13% discount at his local grocery store. What number should he multiply the prices on the tags by to find the price he would have to pay, before tax, in one step?
To find the price that Fwam would have to pay, before tax, in one step, he should multiply the prices on the tags by 0.87.
This is because a 13% discount means that he would pay 100% - 13% = 87% of the original price. So, he would multiply the prices on the tags by 0.87 to find the discounted price.
