Selling price per circuit board $ $187$

Variable cost per circuit board $ $127$

Number of circuit boards:

Produced during the year $21,100$

Sold to outside customers $14,400$

Sold to Division B $6,700$

Sales to Division B were at the same price as sales to outside customers. The circuit boards purchased by Division B were used in an electronic instrument manufactured by that division $($one board per instrument$).$ Division B incurred $$240$ in additional variable cost per instrument and then sold the instruments for $$690$ each.

Required:

Calculate the net operating incomes earned by Division A$,$ Division B$,$ and the company as a whole.

Assume Division A$$s manufacturing capacity is $21,100$ circuit boards. Next year, Division B wants to purchase $7,700$ circuit boards from Division A rather than $6,700.($Circuit boards of this type are not available from outside sources.$)$ From the standpoint of the company as a whole, should Division A sell the $1,000$ additional circuit boards to Division B or continue selling them to outside customers?
