Answer:
<h2>The current year has a cost of $0.50 higher in comparison with last year.</h2>
Step-by-step explanation:
Let's find the rate of change for the graph.
First, we need two points, which are gonna be (0,0) and (8,64).
Then, we use the formula

Then, we replace the points

Therefore, the constant rate of change is 8, which means $8 per bushel of corn.
Now, let's find the rate of change for the table.
We need to points, which are gonna be (2,15) and (6,45).
Then, we use the same formula and replace points

Therefore, the rate of change for the table is 7.5, which means $7.50 per bushel of corn.
Now, by comparison, we notice that the current year has a higher cost than last year. Specifically, this year the cost of a burshel of corn is $0.50 higher in comparison with last year.
