Justice Chung · Answer 1

You need to add 12 pint of yellow.

Step-by-step explanation:

This is the method I used:

There is 4 pint of Yellow (Y) and 4 pint of Blue (B)

because they said is in equal amounts, so they are 50% each.

We need 80% Y and 20% B

so 4:20 = x=80 (4 pints is 20% as "how many pints" is 80%)

So x = 16

We already have 4 pint of Yellow, so we need more 12.
