A business operated at 100% of capacity during its first month, with the following results: Sales (90 units): $90,000 Production costs (100 units): Direct materials$40,000 Direct labor20,000 Variable factory overhead2,000 Fixed factory overhead7,00069,000 Operating expenses: Variable operating expenses$8,000 Fixed operating expenses1,0009,000 The amount of contribution margin that would be reported on the variable costing income statement is a.$26,200 b.$29,700 c.$34,200 d.$20,200

The correct answer is C.

Explanation:

Giving the following information:

Sales (90 units): $90,000

100 units:

Direct materials= $40,000

Direct labor= $20,000

Variable factory overhead= $2,000

Under the variable costing method, the unitary product cost is calculated using the direct material, direct labor, and variable overhead.

We need to calculate the unitary variable cost:

Unitary variable cost= total variable cost/ number of units

Unitary variable cost= (40,000 + 20,000 + 2,000) / 100= $620 per unit

Now, we can calculate the contribution margin:

Total contribution margin= total sales - total variable cot

Total contribution margin= 90,000 - 90*620= $34,200

you have to put the parentheses like this:

in fact, you have to perform the operation inside parentheses first, and then proceed in order:
