Answer to Question #47800 in Algebra for Renee

Question

A farm supply store carries 50-lb bags of both grain pellets and grain mash for
pig feed.
It can store 600 bags of pig feed. At least twice as many of its customers
prefer the mash to the pellets.
The store buys the pellets for $3.75 per bag and sells them for $6.00.
It buys the mash for $2.50 per bag and sells it for $4.00.
If the store orders no more than $1,400 worth of pig feed, how many bags of mash
should the store order to make the most profit? Need to graph as well.
