A large sporting goods store is placing an order for bicycles with its supplier. Four models can

be ordered: the adult Open Trail, the adult Cityscape, the girl's Sea Sprite, and the boy's Trail

Blazer. It is assumed that every bike ordered will be sold, and their profits, respectively, are

$30,25,22,$ and $20.$ The LP model should maximize profit. There are several conditions that

the store needs to worry about. One of these is space to hold the inventory. An adult's bike

needs two feet, but a child's bike needs only one foot. The store has $500$ feet of space. There

are $1200$ hours of assembly time available. The child's bike needs $4$ hours of assembly time;

the Open Trail needs $5$ hours and the Cityscape needs $6$ hours. The store would like to place

an order for at least $275$ bikes.
