The answer is 65+24h. Explanation below.
We will be using (h) to represent the amount of hours. For Jill, the expression will be 45+10h and for Kyle the expression will be 20+14h. Fee+hourly pay x hours.
To get the total amount the company will pay to hire both Jill and Kyle, you must combine both of their expressions. So 45+20= 65, and 10+14=24. So now the expression= 65+24h
So the answer is that the company will be paying 65+24h dollars to hire both Jill and Kyle:)
