The function that represents the total profit for January and February is the sum of them.
We have,
So, the sum would be
Remember that "and" often refers "adding", basically the problem is defining functions for each month, and it wants us to find the combination of both of them
To find the total profit, add p(x) and q(x): (110 + 25x) + (15x + 85) 15x + 25x + 110 + 85 --> group like terms 40x + 195 --> add like terms p(x) + q(x) = 40x + 195 --> This is the function that represents the total profit for January and February
