Answer: Karl must sell 1350 small heaters and 450 large heaters to break even.
We follow these steps to arrive at the answer:
No. Small Large Total
1 Selling Price per unit 80 250
2 Variable Cost per unit 30 120
3 Number of units sold 2100 700 2800
4 Sales mix 3 1
5 Total sales (1*3) 168000 175000
6 Total Variable Cost (2*3) 63000 84000
7 Contribution Margin (5-6) 105000 91000 196000
Next we compute the Weighted Average Contribution Margin as follows:
[tex]\mathbf{WACM per unit = \frac{Total Contribution Margin}{Total number of units sold}}[/tex]
[tex]\mathbf{WACM per unit= \frac{196000}{2800} = 70}[/tex]
Now, Break even point (BEP) is computed as
[tex]\mathbf{BEP = \frac{Total Fixed Costs}{WACM per unit}}[/tex]
[tex]\mathbf{BEP = \frac{126000}{70} = 1800 units}[/tex]
Since the large and small heaters are sold in the 3:1 ratio, we can find the number of large and small heaters to be sold in order to achieve the break even point at 1800 units.
[tex]No. of small heaters = BEP * \frac{3}{4}[/tex]
[tex]No. of small heaters = 1800 * \frac{3}{4} = 1350 units[/tex]
[tex]No. of large heaters = BEP * \frac{1}{4}[/tex]
[tex]No. of large heaters = 1800 * \frac{1}{4} = 450 units[/tex]
