WILL MEDAL AND FAN YOU !!!








Tom's Candy Store has both income and expenses each month. These are shown in the graph below.


Which set of equations represents the number of months and the monthly income and expenses?

Let M = the number of months.
Let D = the monthly dollar amount.
A. Income: M = 1,000D
Expenses: M = 4,500D + 500
B. Income: M = 1,000D
Expenses: M = 500D + 4,500
C. Income: D = 1,000M
Expenses: D = 500M + 1,500
D. Income: D = 1,000M
Expenses: D = 500M + 4,500

Answer 2

its ok lol

Answer 3

Where do the red and blue lines intersect on the graph?

Will you post the coordinates of that point?

Answer 4

x- 9 & Y- 9,000

Answer 5

i think i did that correctly

Answer 6

Yes, you did.

On the Income, 9 months and 9000 dollars means that the Income is 1000 times the number of months. I am having trouble with the assignment of variables.

Would that be I = 1000*D or would it be

I = 1000* M ?

What do you think?

Answer 7

1000*M ?

Answer 8

no, wait .
1000*D.

Answer 9

I have D = 1000 * M for Income but now am confused about Income being a separate variable.
M*
You'd think that Income = M*D period. But, then there is this 1,000

Answer 10

In expenses, we will face the same issue. There is a 500 and a 4500.

The 500 is multiplied by a variable but I don't know if it is M or D.

Answer 11

I think I'll graph the options and see which one looks like the given graph.

Answer 12

ok take your time

Answer 13

Do you see any option that looks like this:

Income: D = 1000*M
Expenses: D = 500*M + 4500

Answer 14

Those are the equations of the lines.

Answer 15

yes ! :D
