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
13-4x=1-x
13=4x+x=1-x+x
13-3x=1
13-1-3x=1-1
12-3x=0
12=3x
12/3=3x/3
4=x
Therefore, x=4

it's like doing those multiplication memory things that had like 100 questions but now with algebra fractions
