Explanation:
For this case we have the following function for the sales

Part a
For this case we want to find the derivate of S respect to t and we got:

Part b
For this case we want to find the value of S when t = 4 so if we replace we got:

Part c
For this case we have the total sales $ 15 millions after t =4 months
Part d

Answer:
Variable cost= $42
Explanation:
Giving the following information:
Each unit is sold for $50
Direct material worth $30
Direct labor worth $5.
Manufacturing overhead cost is $10 per unit of which 70% is variable.
The incremental cost is the variable cost (there is available capacity)
Variable cost= direct material + direct labor + variable manufacturing overhead = 30 + 5 + (10*0.7)= $42
