Question

The table below shows the sale, in dollars, at Jacob's store over a period of five months:

Month
1

2

3

4

5
Sale
1,000

1,050

1,102.50

1,157.63

1,215.51


Did the number of people at Jacob's store increase linearly or exponentially?

Answer 1

Linearly, because the table shows a constant percentage increase in sales per month

Exponentially, because the table shows a constant percentage increase in sales per month

Linearly, because the table shows that sales increase by an equal factor for an equal increase in months

Exponentially, because the table shows an equal increase in sales for an equal increase in months

Answer 2

I think it could be either B or D

Answer 3

I am sticking more towards B @hero

Answer 4

Just need reassurance

Answer 5

How did you go about arriving at B as the answer? What work have you done to prove to yourself that B is correct?

Answer 6

I have completed something along the lines of this because the increase of +50 and the increase of +52.5 are NOT the same, this means we do NOT have a linear function The increases need to be the same each time

Answer 7

SO, I am thinking it could be B

Answer 8

However, I thought that maybe D could work, as it doesn't describe exp. growth - it goes up by a certain percentage each ti

Answer 9

time

Answer 10

Yeah...

Answer 11

It doesn't have to be exactly linear to be linear. It can be "approximately" linear.

Answer 12

What have you calculated to arrive at B as the correct result? Making calculations is more accurate than guessing.

Answer 13

I didnt guess upon B! I gave you my explanation!

Answer 14

Would it be D, then? Or was I right with B?

Answer 15

I am thinking, and surely positive, the answer is D

Answer 16

Where are your calculations? If you didn't calculate anything, you're essentially guessing.

Answer 17

I am not guessing... I asked to see if my answers were correct...

Answer 18

Thats all...

Answer 19

And I was just asking about what calculations you have made to arrive at your choices.

Answer 20

One minute

Answer 21

I have completed something along the lines of this because the increase of +50 and the increase of +52.5 are NOT the same, this means we do NOT have a linear function The increases need to be the same each time

Answer 22

I don't know if this suffices what you want... But

Answer 23

So what calculations have you made that shows these "same increases" you are referring to?

Answer 24

That in order for them to be linear or exponential they must go in an exact direction.

Answer 25

Well, I am just going to go with D then.. As it seems that nobody around here wants to check my work, to make sure I am correct... I am not asking for the answer, I just wanted to justify my own.

Answer 26

You want someone to say whether you are correct or wrong so that you can simply pick the next logical choice.

Answer 27

But you have not made any calculations

Answer 28

Just never mind... I just wanted to fortify my answer, and find out how to do it correctly. It is for my homework, and it is the last question I am missing..

Answer 29

Do you know how to calculate exponential increases? If so, explain

Answer 30

Not really

Answer 31

Which is why I am asking for support

Answer 32

Hang on a minute...

Answer 36

Thank you

Answer 37

I do appreciate the help!

Answer 38

But just to clear up, it is not D, correct? I can cross that one out!

Answer 39

Thank you

Answer 40

If you follow the directions in the video, you'll be able to figure out the correct result on your own.
