The Halters Stable feeds and houses of equestrians. The
stable owner, an ex-racehorse trainer, recognizes the need to set a
nutritional diet for the horses in his care. At the same time, he
would like to keep the overall daily cost of feed to a minimum. The
feed mixes available for the horses’ diet are an oat product, a
highly enriched grain, and a mineral product. Each of these mixes
contains a certain amount of five ingredients needed daily to keep
the average horse healthy. The table below shows these minimum
requirements, units of each ingredient per pound of feed mix, and
costs for the three mixes.
In addition, the stable owner is aware that an overfed horse is
a sluggish worker. Consequently, he determines that 6 pounds
of feed per day are the most that any horse needs to function
properly.
