The Bikini company decided to adopt a different approach to manage the production and selling plans for the upcoming years. It decided therefore to calculate the Break$-$Even Point. Before starting the calculations, some estimations were revised and they are now as follows:

Unitary selling price: $\frac{45}{u}$

Direct material per swimsuit: $7\frac{}{u}$

Direct labour per swimsuit: $4\frac{}{u}$

Variable overhead per swimsuit: $2$ e$/$u

Total fixed factory overhead: $15\mathrm{.}000$

Variable selling commission per swimsuit: $2\frac{e}{u}$

Fixed selling and administrative expenses: $30\mathrm{.}0006$

Given this information:

BEP: $2000u$

BEP: $1407u$

BEP: $1500u$

BEP: $1000u$
