you have 7 pints of green paint, which is made of 50% blue and 50% yellow. that means you mixed 3.5 pints of blue with 3.5 pints of yellow. your goal is to get 65% yellow and 35% blue. you will need 3 more yellow pints, because then you'll have 3.5 + 3 = 6.5 pints of yellow and 3.5 pints of blue, which means your chartreuse paint will be 65% yellow and 35% blue as desired.

so you need 3 more pints of yellow paint to make chartreuse from what you already have.
