The graph shows the prices of different numbers of bushels of corn at a store in the current year. the table shows the prices of different numbers of bushels of corn at the same store in the previous year. previous year number of bushels price of corn (dollars) 2 10 4 20 6 30 8 40 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. 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.

Part A: By finding the ratio of the changes in the price and the changes in the number of bushels will give us the rate of change.

Part B: $2 more is the price of the bushel of corn in the current year compared to the previous year.

Step-by-step explanation:

We have that the graph shows the relation between number of bushels and price of corn (in dollars) for the current year.

Part A: The rate of change of the the bushel of corn in the current year is given by for the points and .

So, using the points (2,14) and (4,28) from the graph, the rate of change for the current year will be,

Rate of change =

i.e. Rate of change =

i.e. Rate of change = 7

So, the rate of change of bushel of the corn for the current year is 7.

Thus, by finding the ratio of the changes in the price and the changes in the number of bushels will give us the rate of change.

Part B: As, we have from the table,

The rate of change of bushel corn using (2,10) and (4,20) is,

Rate of change =

i.e. Rate of change =

i.e. Rate of change = 5

Since, the rate of change of previous year of price is $5 and the current year is $7.

So, we have, $(7-5) = $2 more is the price of the bushel of corn in the current year compared to the previous year.
