Three production processes $-$ A$,$ B$,$ and C $-$ have the following cost structure:$$

the selling price is $9\mathrm{.}79$ per unit

Process

Fixed Cost

per Year

Variable Cost

per Unit

A

$129612$

$2\mathrm{.}63$

B

$97869$

$3\mathrm{.}54$

C

$88642$

$3\mathrm{.}86$

How many units per year must be sold with process B to have annual pre$-$tax profits of $41332$ if the selling price is $9\mathrm{.}79$ per unit? $($Round to the nearest integer$).$
