Consider the following cases:

Case Unit Price Unit Variable Cost Fixed Costs Depreciation

$1$ $ $8,000$ $ $4,800$ $ $15,000,000$ $ $6,750,000$

$24529\mathrm{.}2515,00031,500$

$362\mathrm{.}521,500825$

Ignore any tax effects in calculating the cash break$-$even.

$1$a$.$ Calculate the cash break$-$even point of Case $1.$

$1$b$.$ Calculate the accounting break$-$even point of Case $1.$

$2$a$.$ Calculate the cash break$-$even point of Case $2.$

$2$b$.$ Calculate the accounting break$-$even point of Case $2.$

$3$a$.$ Calculate the cash break$-$even point of Case $3.$

$3$b$.$ Calculate the accounting break$-$even point of Case $3.$
