Question

How do you solve this?.....Katherine has a loyalty card good for a 3% discount at her local grocery store. 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 Katherine would have to pay before tax, she should multiply the prices on the tags by 0.97.

Step-by-step explanation:

To find the price Katherine would have to pay before tax, she should multiply the prices on the tags by 1 minus the discount percentage. In this case, the discount percentage is 3%, so the multiplier would be 1 - 0.03 = 0.97.

For example, if a product has a price tag of $10, Katherine would multiply $10 by 0.97 to get the price she would have to pay before tax: $10 x 0.97 = $9.70.

So, to find the price she would have to pay, before tax, in one step, Katherine should multiply the prices on the tags by 0.97.

Answer 2

Step-by-step explanation:

To find the number Katherine should multiply the prices on the tags by to find the price she would have to pay before tax, we need to calculate the inverse of the discount percentage, which is 1 - (discount percentage / 100).

Given that the discount is 3% and we want to find the price after the discount, that means:

1 - (3/100) = 1 - 0.03 = 0.97

So, the number Katherine should multiply the prices on the tags by to find the price she would have to pay, before tax, in one step, is 0.97. Multiplying the price of an item by 0.97 is equivalent to subtracting 3% from the original price, which is the same as finding the final price after the discount.

For example, if an item is priced at $10, Katherine can multiply this by 0.97 to find that the final price she would have to pay before tax is $9.7

10*0.97 = 9.7
