Given store cost on a loaf of bread is $0.75 and retail price is $3.85.
Discount is always given on retail price.
The amount of discount is 20%
Discount given on $3.85 = 20% of 3.85= .20(3.85)= 0.77.
Cost of bread after discount =3.85-0.77= 3.08
The discounted bread costs $3.08.
The difference in store cost and discounted cost = 3.08-0.75=$2.33
