Long question, I don't even know where to start :/ 5 subparts total

Hyperion Inc., currently sells its latest high-speed color printer, the Hyper 500, for $356. Its cost of goods sold for the Hyper 500 is $193 per unit, and this year's sales (at the current price of $356) are expected to be 20,100 units. Hyperion plans to lower the price of the Hyper 500 to $303 one year from now. Suppose Hyperion considers dropping the price to $303 immediately (rather than waiting one year). By doing so it expects to increase this year's sales by 29% to 25,929 units. What would be the incremental impact on this year's EBIT of such a price drop? Suppose that for each printer sold, Hyperion expects additional sales of $94 per year on ink cartridges for the three-year life of the printer, and Hyperion has a gross profit margin of 71% on ink cartridges. What is the incremental impact on EBIT for the next three years of dropping the price immediately (rather than waiting one year)?
