Hyperion$,$Inc$.,$ currently sells its latest$$ high$-$speed color$$ printer, the Hyper$500,$ for $ $356$$$356.$ It plans to lower the price to $ $309$$$309$ next year. Its cost of goods sold for the Hyper $500$ is $ $205$$$205$ per$$ unit, and this$$ year's sales$($at the current price of $ $356$$$356)$ are expected to be $29$ comma $80029,800$ units.

a$.$ Suppose that if HyperionHyperion drops the price to $ $309$$$309$ immediately$($rather than waiting one$$ year$),$ it can increase this$$ year's sales by $21\%21\%$ to $36$ comma $05836,058$ units. What would be the incremental impact on this$$ year's EBIT of such a price$$ drop?

b$.$ Suppose that for each printer$$ sold, HyperionHyperion expects additional sales of $ $85$$$85$ per year on ink cartridges for the$$ three$-$year life of the$$ printer, and HyperionHyperion has a gross profit margin of $86\%86\%$ on ink cartridges. What is the incremental impact on EBIT for the next three years of such a price$$ drop?
