Hannah wants to buy a wedding cake. The original price is $60. And the tag says 60% off the original price. What is the sale price?

To find the sale price, you need to multiply the original price by the discount percentage.

The discount is 60% off the original price, which means you're paying 100% - 60% = 40% of the original price.
40% of $60 is (40/100) * $60 = $<<40/100*60=24>>24.
Thus, the sale price of the wedding cake is $24. Answer: \boxed{24}.
