Classic Candles handmakes three models of elegant Christmas candles. Santa models require 0.10 day of molding, 0.35 day of decorating, and 0.08 day of packaging and produce $16 of profit per unit sold. Corresponding values for Christmas trees are 0.10, 0.15, 0.03, and $9, while those of gingerbread houses are 0.25, 0.40, 0.05, and $27. Classic wants to maximize profit on what it makes over the next 20 working days with its 1 molder, 3 decorators, and 1 packager, assuming that everything made can be sold.
