Answer:
$2.25
Step-by-step explanation:
You have to set up a proportion to show how much the cost of milk is when discounted per gallon. 0% off, the milk would be $3.75. 40% off, the milk would be x. Now I flipped the percents because that is how much you are actually paying.
Proportion would look something like this:
3.75/100 = x/60
solve for x:
225 = 100x
x= 2.25
