Answer:
The overall Sales revenue at break even is $515995.872
Step-by-step explanation:
The overall break even in dollars or the composite break even point is the Total revenue that a business must earn from all its products that should be equal to the total costs from all its products and there is no profit or no loss.
The formula for composite or overall break even in dollars is,
Break even in dollars = Fixed costs / Weighted average contribution margin ratio
Where the weighted average contribution margin ratio is the weghtage of each product in the overall sales mix multiplied by the contribution margin of each product.
The total sales mix is = 8 + 4 + 1 = 13
Weighted average contribution margin ratio = ((360 - 210) / 360) * 8/13 +
((500 - 300) / 500) * 4/13 + ((1600 - 600) / 1600) * 1/13 = 0.5814 or 58.14%
Break even in dollars = 300000 / 0.5814
Break even in dollars = $515995.872
If there is some discrepancy in the final answer, it will be due to the rounding off of the weighted average contribution margin ratio
