Analyzing Income under Absorption and Variable Costing

Variable manufacturing costs are $13 per unit, and fixed manufacturing costs are $75,000. Sales are estimated to be 12,000 units.

If an amount is zero, enter "0".

a. How much would absorption costing income from operations differ between a plan to produce 12,000 units and a plan to produce 15,000 units? $

b. How much would variable costing income from operations differ between the two production plans? $

A- Is NOT 3,750. Thank you.
