Question

please help
Jess plans to increase the amount of money she saves each month. She can increase her savings in the following ways:
Month 1 2 3 4 5
Option 1 20 22 24.2 26.62 29.28
Option 2 20 22.2 24.4 26.6 28.8
Option 3 20 24 28.8 34.56 41.47


If Jess wants to increase her savings exponentially, which option(s) should she choose?

Only option 1, because it shows equal increases in equal intervals of time.

Only option 2, because it shows equal increases in equal intervals of time.

Either option 1 or option 3, because they show increases in time by the same percenta

Answer 1

Either option 2 or option 3 because they show increases in time by same percentages

Answer 2

Yeah but the rate of increase should be constant.

Answer 3

That was another option

Answer 4

What methods did you use to come up with the rate or percent increase?

Answer 5

Dividing

Answer 6

22 from 20

Answer 7

Did I solve it correctly????

Answer 8

What did you divide exactly? Explain what you did in detail.

Answer 9

I did ivied 22/20

Answer 10

Multiplied that answer by each one to see what if it's exponential

Answer 11

Basically, what you should do is, begin with option 1 and divide each set of options consecutively starting with the 5th and 4th options:

29.28/26.62 = 1.1

Then the 4th and 3rd options
26.62/24.2 = 1.1

Then the 3rd and 2nd options:
24.2/22 = 1.1

Then the 2nd and 1st options:
22/20 = 1.1

Notice that the rate of increase is the same for each

So we know that at least option 1 is correct.

Answer 12

Perform the same sequence of operations for the 2nd and 3rd options to see if they also have a constant rate of increase for each interval.

Answer 13

@THEGAMER607,

I deleted your answer, so the medal you received has been taken away and you will not receive any credit for just giving the answer. In fact, the only thing that will have been accomplished here (if it can even be called an accomplishment) is that the user will have been given the answer without any explanation or understanding of how to arrive at the correct answer on his or her own in similar problems without help. Basically, in this case, no facilitating, guiding, or demonstration of the process of learning in relation to problem solving was given which means, the user didn't learn anything and ultimately, the foundational goals of Open Study have been compromised. Therefore, I recommend that you re-evaluate your approach to helping students here. Otherwise, more appropriate actions will be taken to resolve this issue.


We as humans are naturally inclined to be lazy often times when someone else (of considerable influence) around us is being lazy. And particularly young people as they are influenced by others. Thus more you demonstrate "laziness" when helping other users, the more inclined (to be lazy) other users will be when doing their homework. That's why, when a user is present, you should take advantage of the opportunity to facilitate and demonstrate the appropriate problem solving approach and the process of learning as much as possible, because how you facilitate is what they will remember in their experience with Open Study. If when they come here, you do all the work for them, they will think that all they have to do is simply post their question and all the work will be done for them and that they don't have to do anything else except just kick back, watch, and observe. However, if you involve them in the process, then they will understand that being involved is part of the way things work here.

Answer 14

I solved the problem by myself on my own, I took option 1 and 3 and discovered they were exponential and did the same thing with option 2 NAND discovered it was linear. I am not lazy I am actually a very hardworking student and I DONOT appreciate you assuming things about a person you know nothing of. Thank you for your time. I know that I didn't cheat and that's all that matters my opinion only.

Answer 15

Oh I apologize @hero I thought you were directing that comment net toward me

Answer 16

@kristinak, I definitely was not referring to you .

Answer 17

I'm so sorry I didn't read it completely

Answer 18

And I had already solved the problem before the guy placed the answer on my own, but thank you for your time

Answer 19

May you assist me on another problem?

Answer 20

@Hero ok sorry i didnt know im only 11

Answer 21

Interesting since Open Study is only welcome to users age 13+

Answer 22

@Hero im here just to learn new things because my i learn to advanced an I wanted to learn more

Answer 23

Every user is expected to abide by the guidelines established in Open Study's code of conduct.

Answer 24

*Im here just to learn new things because I learn too advanced and I wanted to learn more
