Trying so hard to help my sister here haha haven't been in the 7th grade for a LONG time. Can y'all help me out?

Answer 1

Not sure if this is it, but this is my take on it..
(1x+4.25y + 2.5z) = 1 pint of purple icing
x=y=z

so if you want 2 pints of purple icing..
(1(2)+4.25(2)+2.5(2))
so 8.5 of blue food coloring and 5 of red food coloring
