Tina painted a mural for St. Patrick's Day and mixed her own green paint. She
used a
ratio of 3 parts yellow to 2 parts blue.
Kayla also wanted to paint a mural with
the same green color, but she currently has 8 cups of
green paint that is a mixture of
40
%
yellow paint and 60% blue paint. To get the same
shade of green as Tina, how many
cups of yellow paint must Kayla add to her mixture
?
