purchase of weapons for the military
Answer:
a) 
b) 
c) For this case we have the total sales $ 15 millions after t =4 months
d) 
e) This value represent the increase in the amount of sales in millions after t=4 months
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
For this case we just need to replace t=4 in the derivate and we got:

Part e
This value represent the increase in the amount of sales in millions after t=4 months
Answer:
The firm should increase output and reduce price
Explanation:
For a monopolist, there can be one of the following three scenarios at a time point in time:
Scenario one, MR = MC: For a monopolist, profit is maximized at the point where marginal revenue (MR) is equal to to marginal cost (MC), i.e. where MR = MC.
Scenario two, MR < MC: But when the MR < MC, it indicates that the monopolist is currently producing a higher quantity of output and it is not maximizing profit. In order to maximize profit, the monopolist has to reduce output until MR = MC.
Scenario three , MR > MC: But when the MR > MC, it indicates that the monopolist is currently producing a lower quantity of output and it is not maximizing profit. In order to maximize profit, the monopolist has to increase output until MR = MC. Also, the monopolist has to reduce price in order to sell the increased quantity of output.
From the question, the monopolist falls into scenerio three as MR > MC, i.e. $45 > $35. Therefore, the monopolist should increase output until MR = MC and reduce price in order to maximize profit.
