Answer:
3100 units of Product Z
Explanation:
The ratio is 4 is to 2, that means:
4 + 2 = 6 parts total
Now,
We have to cover the fixed cost of 418,500 from profits, that is SP - VC
Where SP is Selling Price and VC is Variable Cost
Product A:
SP = 75
VC = 35
Profit = 40
Product B:
SP = 95
VC = 40
Profit = 55
So, we can sell "4x" of product A and "2x" of product B, and create the equation:

Now, we solve for x:

The amount of Product Z was taken as "2x", so the quantity of Product Z would be:
2(1550) = 3100 units of Product Z
