Formulate the following as a linear program.
Joe’s Sports Shop is sponsoring a weekly boomerang-throwing contest as part of its
spring promotions. Anyone may enter, but the boomerangs used must be purchased at
the shop. Demand is unlimited. Two models can be made: the regular model (with a
profit of $2 each) and the super model (which yields a $5 profit). However, production
facilities are limited. A regular boomerang requires 1 hour of carving and 2 hours of
finishing, while a super boomerang takes 3 hours to carve and 2 hours to finish. The
skilled crafters employed by the shop have indicated they will spend no more than 75
hours carving and 100 hours finishing boomerangs per week. The owner wishes to
allocate production in order to maximize profits.
