Question

Shirts are on sale for 20%.You buy 2 of them. As you pay, the cashier says, “20% off of each shirt means 40%off the total price.” Do you agree or disagree? Please explain thoroughly.​

Answer 1

Explanation:

Disagree.

If each shirt is originally x dollars, then the new price is 0.8x. So the total cost is 1.6x, down from the original 2x.

So the discount is (2x − 1.6x) / 2x × 100% = 20%.
