Answer:
A. The number of boxes that can be packed by Ryan and Daniel each increases over time. Daniel's function has a greater rate of
change than Ryan's function indicating that Daniel can pack more boxes per hour.
Step-by-step explanation:
Given
Ryan: 3 boxes per hour
Daniel: 
Required
True statement about their functions
First, we calculate Ryan's function.
In 1 hour, he can pack 3 boxes.
In hours, he can pack 3h boxes.
So, the equation is:

So, we have:
---- Ryan
--- Daniel
Both functions represent direct proportional functions.
So, when h increases y also increases.
<em>However, Daniel's function has a greater rate of change because</em>
<em> implies that he can pack 4 boxes per hour while Ryan can pack 3.</em>
