A clothing shop is having a 40% off sale. How much would a shopper have to play for a $50 sweater with a 40% discount?

30

Step-by-step explanation:

If we get 40% off, we still have to pay 100-40% = 60%

Take the original price * the percent we have to pay

50 * 60%

Change to decimal form

50 *.6

30

We have to pay $30
