Jane paid $40 for an item after she received a 20% discount. jane's friend says that this means that the original price was $48. a) how do you think jane's friend arrived at this amount? b) is her friend correct? why or why not?

A) She must have used 20% from the $40 instead of the unknown price.

B) No, because: see below explanation.

Step-by-step explanation:

X is the original price.

If $40 is 80% of x, to find 1% of the price, divide $40 by 80.

You will get $0.50 for 1%.

To find the full amount, just multiply that by 100.

0.50*100= 50.

Total: $50.
