Answer and Explanation:
The computation of the payback period for each investment is shown below;
For Option 1
= Initial Investment ÷ Annual Cash Flow
= $280,000 ÷ $134,569
= 2.081 Year
Here Annual cash inflow is
= Net income + Depreciation
= $80,769 + (($280,000 - $11,000) ÷ 5)
= $134,569
For Option-2
= Initial Investment ÷ Annual Cash Flow
= $200,000 ÷ $70,429
= 2.84 Year
Here Annual cash inflow is
= Net income + Depreciation
= $44,000 + (($200,000 - $15,000) ÷ 7)
= $70,429
The break even point in composite units is 5000 units.
Break even point
The Break-even point is calculated by dividing the fixed cost by the contribution margin per unit.
For this sales mix, the contribution margin per unit is the aggregate of each contribution margin. Contribution margin is calculated by subtracting variable cost from the selling price
Contribution margin for A is $20- $12 = $8 x 3 units
Contribution margin for B is $ 30 - $18 = $12 x 2 units
Contribution margin for C is $40 -$24= $16 x 1 unit
Total contribution margin per unit will be
(8 x 3) x (12 x 2 ) x( $16 x 1)= $64
Break-even point = $320,000 /64
