Use all mass units either as ounces or as pounds.

BLUE BEADS, 0.50 per ounce
GREEN BEADS, 0.75/16 per ounce
Mixture, 0.55/16 per ounce

Reason for choosing dollars per ounce is because the question asks how many ounces of each.

Form these equations to account for mass and price:
b, ounces of BLUE beads
g, ounces of GREEN beads
