A shop is giving 20% discount in a sale. A shirt in the shop normally costs $60. How much does it cost in the sale?

20 percent of 60 is 12 60 dollars minus 12 is? That's your answer.

Since the shop is giving 20% discount, that means the paid amount would actually

be (100 - 20) % = 80 %

So for a $60 shirt, amount = 80% of 60

= (80/100) x 60

= (8/10) x 60

= 48.

Cost in sale = $48.

Cheers.
