Let me break this up.
Note: (f o g)(2) = f(g(2)).
Note: g(2) = (2, 2) means when x is 2 y is 2.
In other words, g(2) is 2.
We know that f(g(2)) = f(2).
You can see that f(2) = -3. This is given in the point (2, -3).
So, f(g(2)) = -3.
Done.
The wall can be built in 22 days by 6 workers in first 6 days and 9 workers in the rest of time.
<h3>How to use inverse proportionality to determine building time of a wall</h3>
In this question we must use the definition of <em>inverse</em> proportionality, in which the number of workers (
), no unit, is inversely proportional to the <em>building</em> time (
), in days.
According to the statement, 6 workers spent 6 days building a wall and there are 24 days left for completion, but 3 more workers entered to reduce building time, which can be represented by the following expression:


In this scenario, the wall can be built in 22 days.

Answer:
15 % profit
Step-by-step explanation:
CP = SP - profit
= 115 - 15
= 100
Profit% = Profit / CP × 100
= 15 / 100 × 100
= 15%
