Answer:
Part A: 8 dollars/brushel
Part B: 1 dollar/brushel
Step-by-step explanation:
Without reading the question you can already conclude that this is a linear equation. Also, we can easily get the linear function:

Part A: Describe in words how you can find the rate of change of a bushel of corn in the current year, and find the value.
We know that a linear function has a constant rate of change, and that is called SLOPE.
In order to calculate the slope of the linear function:

<u>Therefore, </u><u>the rate of change of a bushel of corn in the current year is 8</u>
<u></u>
Part B: How many dollars more is the price of a bushel of corn in the current year than the price of a bushel of corn in the previous year? Show your work.
<u>Previous Year Number of Bushels Price of Corn (dollars)</u>
Ordered pairs:

Let's calculate the slope again.

<u>The difference is 1 dollar/brushel.</u>
