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 the Number of Bushels on the x-axis and the Price of Corn in dollars on the y-axis. The x-axis scale is shown from 0 to 14 at increments of 2, and the y-axis scale is shown from 0 to 98 at increments of 14. A straight line joins the ordered pairs 2, 14 and 4, 28 and 6, 42 and 8, 56 and 10, 70 and 12, 84.
Previous Year
Number of Bushels
Price of Corn (dollars)

20
6

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.

Answers

Answer:Part A:8 Part B:$1

Step-by-step explanation:

Part A: 7 dollars

- The graph shows that 2 bushels is 14 dollars, because the graph has a straight line, the rate remains constant you must divide the sides by two to find the amount for one bushel which would be 7 dollars.

- And to double check you would divide 28 by 4, 42 by 6, 56 by 8, 70 by 10, 84 by 11, and 98 by 12. they all equals 7 dollars So, the equation would be y = 7x.

- 7 can be known as the slope and rate of change.

Part B:2 dollars

- The years before show 2 bushes was 10 dollars

-so you would divide 10 by two you would get five To double check you would do the same thing with 20 by 4, 30 by 6 and 40 by 8, and they all equal 5 dollars.

-if you use this answer be sure to reword it so you dont get copy write and integrity. have a great day or night.

Please help, I would really appreciate it!

Find the price of the candy bar if it is sold with a 65% mark up
A. $1.58
B. $1.44
C. $1.30
D. $1.17

Answers

Answer:

C. $1.30

Step-by-step explanation:

Multiply 0.79 and 0.65 (65%) which is about 0.51.

Add that to 0.79.

Answer:

$ 1.30

Step-by-step explanation:

Increased price = 65% of $0.79

[tex]\frac{65}{100}*0.79[/tex]

= 0.65 * 0.79

= 0.5135

= $ 0.51

Selling price = 0.79 + 0.51 = $ 1. 30
