Answer:
Produce only Product B.
Step-by-step explanation:
The contribution margin per machine hour for product A is ...
($16 -$6)/(5 hour) = $2 per hour
The contribution margin per machine hour for product B is ...
($12 -$5)/(3 hour) ≈ $2.33 per hour
The company should produce the maximum possible number of the product that contributes the most per machine hour: Product B.
4.12 is equal to
4+ 12/100
Now to convert a mixed number to an improper fraction the rule is:
a b/c=(ac+b)/c so we have
412/100
103/25
