Accelr$8$ LLC faces a capacity constraint. Specifically, a machine has broken down and cannot be used to satisfy customer demand. Accelr$8$ thus had to prioritize its production of its two products, Warp and Hyper. It decided to make ALL of Warp to satisfy demand, but only part of Hyper $-$ in light of the constraint.

Information for each product is below:

Contribution margin per unit, Warp is $$20$ per unit, and Accelr$8$ could make $15$ units per hour.

Contribution margin per unit, Hyper is $$15$ per unit, and Accelr$8$ could make $12$ units per hour.
