Answer:
E) 0 units of A and 200,000 units of Z.
Explanation:
In order to estimate the profit maximizing sales mix we first calculate the contribution per product per limiting factor. Limiting factor in this case is the labor hours.
So,
Contribution per hour if A is made = 8 * 12 = $96
Contribution per hour if Z is made = 10 * 10 = $100,
Therefore Z holds priority,
Since there is no sales mix we need to follow we can just make Z for maximizing profits and as such We make 20000 * 10 = 200,000 units of Z and 0 units of A.
Hope that helps.
