Answer:
The amount off the original price is $3.6.
Step-by-step explanation:
The original price of the sweater = $18.00
Amount off on the sweater = 20% of the original price of the sweater
=[tex]18.00\times\frac{20}{100}=$3.6[/tex]
The cost of the sweater on the sale = $18.00 - $3.6 = $14.4
The amount off the original price is $3.6.
