Minimum cost

Two machines produce the same item. Machine A can produce 15 items per/hr and Machine B can produce 10/hr. At least 420 of the items must be produced each 40-hr. week, but the machines cannot be operated at the same time. If it costs $50 per hour to operate A and $30 per hour to operate B, determine how many hours per week to operate each machine to meet the production requirement at minimum machine cost.

Solution Summary

This shows how to share work between machines to meet requirements at minimum cost.
