Division A manufactures electronic circuit boards. The boards can be sold either to Division B of the same company or to outside customers. Last year, the following activity occurred in Division A:

Selling price per circuit board $ $176$

Variable cost per circuit board $ $125$

Number of circuit boards:

Produced during the year $21,300$

Sold to outside customers $14,200$

Sold to Division B $7,100$

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 $$210$ in additional variable cost per instrument and then sold the instruments for $$690$ each.

Required:

$1.$ Calculate the net operating incomes earned by Division A$,$ Division B$,$ and the company as a whole.

$2.$ Assume Division A$$s manufacturing capacity is $21,300$ circuit boards. Next year, Division B wants to purchase $8,100$ circuit boards from Division A rather than $7,100.($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 to sell them to outside customers?
