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.

A graph shows Number of Bushels on x-axis and Price of Corn in dollars on y-axis. The x-axis scale is shown from 0 to 21 at increments of 3, and the y-axis scale is shown from 0 to 168 at increments of 24. A straight line joins the ordered pairs 3, 24 and 6, 48 and 9, 72 and 12, 96 and 15, 120 and 18, 144.

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. (5 points)
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 in words. (5 points)

A.  $8

B.  $1

Step-by-step explanation:

Part A:

Rate of change of any graph maybe interpreted by the gradient. In this case, since the line passes through origin, the gradient is:

The price this year is $8.

Part B:

Similarly, price in the previous year was

Change is $8 - $7 = $1  per bushel.

Part A:

The rate of change of the current year can be found taking the price of corn for that year and divide that by its respective number of bushels.

For example: It costs $48 to buy 6 bushels of corn, so 48/6=$8

So it's $8 per bushel for the current year

Part B:

The price of a bushel of corn is $1 more than in the previous year. The rate of change for the previous year is $7 per bushel while in the current year it is $8 per bushel. Since 8-7=1, this confirms that it's true.

no he doesnt because "-16' is negatiive

step-by-step explanation:

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
