Final answer:

The function h(x) = 2.55x + 8.03 represents the difference between the amounts Julia and Kellen will raise when they both read x pages.

Step-by-step explanation:

The function h(x) = 2.55x + 8.03 represents the difference between the amounts Julia and Kellen will raise when they both read x pages. This function calculates the difference in dollars between the amount Julia would raise based on the number of pages she reads (1.65x + 17.31) and the amount Kellen would raise based on the number of pages he reads (0.90x+9.28).

To find the difference, you simply subtract the amount Kellen would raise from the amount Julia would raise. So the correct function is h(x) = 2.55x + 8.03.
