your answer tells you about a $$1$ decrease in estimated variable costs.

Scenario Analysis $[$LO$2]$ In the previous problem, suppose the projections given

for price, quantity, variable costs, and fixed costs are all accurate to within $+-10$ per$-$

cent. Calculate the best$-$case and worst$-$case NPV figures.

Calculating Break$-$Even $[$LO$3]$ In each of the following cases, calculate the ac$-$

counting break$-$even and the cash break$-$even points. Ignore any tax effects in calcu$-$

lating the cash break$-$even.
