a$.$ Calculate the breakeven point for each firm in terms of revenue.

b$.$ What observations can you draw by examining the breakeven point of each firm given that they earned an equal amount of operating income on identical sales volumes in $2022?$

c$.$ Calculate the amount of operating income $($or loss$)$ that you would expect each firm to report in $2023$ if sales were to

Increase by $20\%.$

Decrease by $20\%.$

d$.$ Using the amounts computed in requirement c$,$ calculate the increase or decrease in the amount of operating income expected in $2023$ from the amount reported in $2022.$

e$.$ Explain why an equal percentage increase $($or decrease$)$ in sales for each firm would have such differing effects on operating income.

f$.$ Calculate the ratio of contribution margin to operating income for each firm in $2022.($Hint: Divide contribution margin by operating income.$)$

g$.$ Multiply the expected increase in sales of $20\%$ for $2023$ by the ratio of contribution margin to operating income for $2022$ computed in requirement $f$ for each firm. $($Hint: Multiply your answer in requirement $(f)$ by $0\mathrm{.}2.)$

h$.$ Multiply your answer in requirement $g$ by the operating income of $$300,000$ reported in $2022$ for each firm.

i$.$ Compare your answer in requirement $h$ with your answer in requirement $d.$ What conclusions can you draw about the effects of
