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

Explanation:
(I) According to the demand law, <em>if the price of tea increases the quantity demanded of tea will decrease</em>. If the price of tea decreases, the quantity demanded of tea will increase. Quantity demanded and the price has an inversely proportional relationship in the demand law.
(II) When talking about complementary goods like tea and sugar, <em>if the price of tea increases will result in a negative movement along the demand curve of tea and will cause the demand curve of sugar to move inwards. In such a scenario, the demand for each good will be reduced.</em>
