Answer:
$0.75
Step-by-step explanation:
Given
Normal price - $3.70
If Hamburger is on sale for 20% off the normal price
The amount that can be saved will be 20% of $3.70
Amount that can be saved = 20/100 * 3.70
Amount that can be saved = 1/5 * 3.70
Amount that can be saved = 3.7/5
Amount that can be saved = 0.75
Hence the Amount that can be saved on $3.70 is $0.75
