Hi,
The answer will be D.. 120 units of product Y only.
Here we need to find the contribution margin as well as the contribution margin per limiting factor.
Here the limiting factor is qty (lbs) of materials.
Now for product X and Y, the CM per LF.
X = 200  176 =24
Y = 250 200 =50
Limiting factor
for X = 1200/8 =150 units
For Y = 1200/10 =120 units
So CM per LF for
X = 24/150 = 0.16
Y = 50/120 =0.42
So it's evident that CM per LF is more for product Y. So we need to produce entire units of Y.
Now we need to check how many units are remaining after production of X
Here for Y no of units is 120 and RM required per unit is 10 so total units produced is 1200 lbs.
Required units is 1200 lbs only. So no need to produce Product X.
