Answer:
400; 800
Step-by-step explanation:
Contribution:
Product X:
= Selling price - Variable cost
= 100 - 70
= 30,
Product Y:
= Selling price - Variable cost
= 80 - 40
= 40,
Product Z:
= Selling price - Variable cost
= 25 - 20
= 5
Machine hours required :
Product X:
= Machine time per unit × Monthly demand
= 3 × 300
= 900,
Product Y:
= Machine time per unit × Monthly demand
= 2 × 200
= 400,
Product Z:
= Machine time per unit × Monthly demand
= 1 × 500
= 500
Contribution per machine hour:
Product X = Contribution ÷ Machine time per unit
= 30 ÷ 3
= 10,
Product Y = Contribution ÷ Machine time per unit
= 40 ÷ 2
= 20,
Product Z = Contribution ÷ Machine time per unit
= 5 ÷ 1
= 5
It is highest for Y, so produce maximum amount of Y, then X and then Z
Y needs 400 hrs, we are left with 800 hours, so produce 800 hours of X.
