Question

You probably know how to make green from blue and yellow, but how do you make chartreuse? If you find 7 pints of green paint in your garage, made from equal amounts of yellow paint and blue paint, you’d have to add more yellow to make chartreuse. The mixture needs to be 65% yellow. How much more yellow paint needs to be added to the can to make chartreuse? ____ pints

PLEASE HELP

Answer 1

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.
