The bolded portion here might give away potential answers:
If you increase the price of the good that you are selling, your total revenue increases, but your total profit decreases. Supposing that your demand has not changed, what do these two facts imply for price elasticity of demand and your cost structure
One answer could be volume. An example of this is, let's say that general motors makes a profit of $1,000 per vehicle sold. Under these circumstances GM's profit may be dependent upon the number of units they sell moreso than it is their total revenue.
Imagine a scenario where cars manufactured by GM cost an average of $5,000 and they raise the price to $7,000 (or another arbitrary number) with their profit per vehicle remaining $1,000. There could be a scenario where their gross revenue increases while their net revenue decreases off of a diminishing number of total cars sold.
Also if the price of their cars was $5,000 and it was raised to $7,000 with the profit per vehicle remaining $1,000 that could imply their cost structure was scaled in a way where liabilities and price were strongly correlated due to fundamental business model, etc.
