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

3:5=x:50

Therefore 5 ×x = 50

x = 10

Therefore 3 × 10 = 30

therefore 30 blue pens

proof = 30 blue + 50 red= 3+ 5

therefore 80 = 8x
