Required:

A nationwide discount chain has approached Macro with an offer to buy $2,000$ Lightning $2\mathrm{.}0$ computers and $2,000$ Lightning $2\mathrm{.}4$ computers if the unit prices are lowered to $$350$ and $$450,$ respectively.

If Macro accepts the offer, how many direct labor$-$hours will be required to produce the additional computers?

How much will the profit increase $($or decrease$)$ if Macro accepts this proposal? All other prices will remain the same.

Suppose that the customer has offered instead to buy up to $3,000$ each of the two models at $$350$ and $$450,$ respectively.

How many of each product should be manufactured and sold? Assume current demand will not be affected by the special order. Also assume that the company cannot increase its production capacity to meet the extra demand.

How much will the profits change if this order is accepted instead?
