Howard buys a new comforter set for 15% off the original price of 54$.What is the sale price?
Stolb23 [73]

Answer:

$45.90

Step-by-step explanation:

What 15% off means is 85% of the original price ($54). 85% is the same as 17/20. Multiply 17/20 by 54 (or multiply 3/20 by 54 and subtract that from 54) to get the sale price.

(17 * 54)/20 (Multiply 17 by 54)

918/20 (Reduce if needed)

459/10 (Divide 459 by 10)

45.9

The sale price of the comforter is $45.90.
