I do not need code for this. The Mill Mountain Coffee Shop blends coffee on the premises for its customers. It sells three

basic blends in $1-$pound bags, Special, Mountain Dark, and Mill Regular. It uses four different

types of coffee to produce the blends $-$ Brazilian, mocha, Colombian, and mild. The shop has the

following blend recipe requirements:

The cost of Brazilian coffee is $$2\mathrm{.}00$ per pound, the cost of mocha is $$2\mathrm{.}75$ per pound, the cost

of Colombian is $$2\mathrm{.}90$ per pound, and the cost of mild is $$1\mathrm{.}70$ per pound. The shop has $110$

pounds of Brazilian coffee, $70$ pounds of mocha, $80$ pounds of Colombian, and $150$ pounds of

mild coffee available per week. The shop wants to know the amount of each blend it should

prepare each week to maximize profit.
