I was wondering if any of you could solve the following equation,
Green paint and yellow paint can be mixed in the ratio 4:7 to make a certain lime colored shade. If a painter has 500 ml of green and 650 ml of yellow, what volume of lime colored paint can be made?
I have tried to solve this by using up all the green paint, and then using what is left of the yellow paint, however, I get confused when I do this. I also tried to add 500 and 650 to make it easier, but this does not work either.
Thank a lot!
