School days

Readers, in case you are wondering what seventh grade math is like these days, here:

A painter has exactly 32 units of yellow dye and 54 units of blue dye. She plans to mix the dyes to make two shades of green. Each gallon of the lighter shade of green requires 4 units of yellow dye and 1 unit of blue dye. Each gallon of the darker shade of green requires 1 unit of yellow dye and 6 units of blue dye.

 Make a graph showing the number of gallons of the two greens she can make.

List three possible solutions.
