Given:
The graph shows the prices of the current year for the number of bushels.
And the table shows the prices of the previous year.
Part A: We will find the rate of change of bushels of corn in the current year.
As the graph shows a line, so, the rate of change will be the slope of the line
We will find the slope using two points.
As shown the line passes through the points (0,0) and (3,24)
So, the slope will be as follows:
[tex]slope=\frac{24-0}{3-0}=\frac{24}{3}=8[/tex]So, the rate of change = $8 per Bushel.
Part B: How many dollars more in the price of a bushel of corn in the current year than the previous year.
From the table: the price of the previous year = 21/3 = $7
And form the graph, the price of the current year = $8
So, the differnce = 8 - 7 = $1
So, the answer will be:
$1 more is the price of the current year than the price of the previous year.
