Question

Jane paid $40 for an item after she received a 20% discount. Jane's friend says this means that the original price of the item was $48. Determine if Jane's friend is correct about the original price of the item.

Answer 1

she is incorrect because if she was given a 20% discount the amount she would have to pay is 38.4

Explanation:

48 x .2 = 9.6

48 - 9.6 = 38.4 not 40

Answer 2

Jane's friend's assumption about the original price was incorrect.

Explanation:

A price of $40 after being given a 20% discount would end up being $50 instead of $48. This is because 20% of $50 is $10, and that is what was deducted from the price to make it $40.
