It costs Vaughn Company $26 per unit ($18 variable and $8 fixed) to produce its product, which normally sells for $38 per unit. A foreign wholesaler offers to purchase 4800 units at $21 each.

(a) If the special order is accepted, what will be the effect on net income?

Effect on income= $4,800 increase

Giving the following information:

Unitary variable cost= $18

A foreign wholesaler offers to purchase 4800 units at $21 each. Vaughn would incur special shipping costs of $2 per unit if the order were accepted.
