Tyannamj:

I need help with a math problem.

itzzalyssa:

what kind

Tyannamj:

College Algebra

itzzalyssa:

uhhh im in 7th grade so i cant help you with that sorry

snowflake0531:

can you post hte screenshot, so someone can help if they can

Tyannamj:

Part 1: Explain which companies would advertise APR over APY and describe how this would help them attract customers. (4 points) Part 2: Create a unique APR (state how often the rate is compounded) and calculate the corresponding APY. Use a comparison of the two rates to verify your answer to part 1. (4 points)

snowflake0531:

@AZ if you know finance xd

Tyannamj:

I don't lololololll

snowflake0531:

xddd, that's why i tagged someone else, idk either

Tyannamj:

I tried using that its so confusing idek

snowflake0531:

Do you know the difference between APR and APY?

Tyannamj:

nope I don't know anything lmao

snowflake0531:

google xdd

Tyannamj:

I have part 1 I just need part 2

snowflake0531:

Well, you'll first need to think of like a random scenario with random numbers and stuff, for example, what do you want the interest to be, the time, etc.

Tyannamj:

a random number? what about 7

snowflake0531:

In this screenshot, you can see that you need an interest amount, a period of time, and the principal amount To get the interest amount, you need time, which means like think of for how long of a span do you want this for, using that, you can think of an interest rate, and then calculate the interest? and then put those all into the equation?

Tyannamj:

so I can just pick random things to enter in that equation

snowflake0531:

Uh, kinda, like, you have to know that like..... the time... rate.... interest.... and to write those values down, because you ahve to use the same numbers and stuff to calculate APY

Tyannamj:

yikes idk

snowflake0531:

Hmm, I think that APY will be easier to calculate, I just tried to xd, altho i'm notsure if I did right or not lmao

snowflake0531:

For example, you can calculate the rate to be 7%, and the periods per year tobe 4 times So, 7% interest 4 times a year, putting that into the equation it would be (1+(0.07/4))^4 -1

snowflake0531:

From ^^^ I get 0.07185903128, which is about 7.2% ig Idk

Tyannamj:

okkkkkkkk thanks!!!!

snowflake0531:

xdxdxdxdxdddd but then APR confuses me... that equation looks much... harder to do ig

snowflake0531:

lemme first try it myself xd and tehn if i get it i'll post it

Tyannamj:

okay, thank you

snowflake0531:

wait wait wait wait for the APR i'll need a principal amount- but APY doesnt need it, i'm confused again

Tyannamj:

yeah I don't even understand my math class rn

snowflake0531:

If one equation is vastly different from teh other, one has and the other doesn't have the principle amount, won't the thing change? bc looking at it again, all you really need to do is interest/principle times 100 so if i need a principle amount, it'll be really different

snowflake0531:

you're in college?

snowflake0531:

OHHHHHHHH nermind, because the numerator depends on the denominator and such, the principal amount doesn't matterxdddd, well, it does but like-

Tyannamj:

no I'm in high school

snowflake0531:

kek, i got 28 percent what the heck

snowflake0531:

oh

Tyannamj:

haha idkkkk

snowflake0531:

xdxdxdxdddd So, I stayed with 4 periods, 7% interest rate, maybe i did the find interest part wrong._. i'm not sure if i'm supposed to do it using compound interest or simple interest

snowflake0531:

And I also dk whether I should find the interest annually or quarterly since I'm sticking with n=365 so I don't' have to multiply it by 365 later

Tyannamj:

compound I think

snowflake0531:

oof

snowflake0531:

then i'd do it quarterly k

snowflake0531:

wait so that confuses me again, am i getting teh interest or am i subtracting the interest xd

Tyannamj:

actually you can do whatever

Tyannamj:

my teacher just asked make up your own scenario

Tyannamj:

Create a unique APR (state how often the rate is compounded) and calculate the corresponding APY. Use a comparison of the two rates to verify your answer to part 1.

snowflake0531:

Principle: 1000 Quarterly/4 times Time: one year/365 days Interest rate: 7% First time: 70 dollars - left with 930 Second time: 65.1 - left with 864.9 Third time: 60.543 - left with 804.357 Fourth time: 56.30499 - 748.05201 Now we fidn the whole amoutn of interest taken away 70 + 65.1 + 60.543 +56.30499 = 251.94799 And then since we did 365 days, we can cross simplify it so we only do interest/principle So 251.94799/1000 = 0.25194799 Which is about 25%

snowflake0531:

and then idk, the first one was like 7% this one is like 25% i have no idea what you're comparing but like-

Tyannamj:

omg thank you

snowflake0531:

kek, but i'm probably wrong tho lmaoooo

Tyannamj:

Principle: 1000 Quarterly/4 times Time: one year/365 days Interest rate: 7% First time: 70 dollars - left with 930 Second time: 65.1 - left with 864.9 Third time: 60.543 - left with 804.357 Fourth time: 56.30499 - 748.05201 Now we fidn the whole amoutn of interest taken away 70 + 65.1 + 60.543 +56.30499 = 251.94799 And then since we did 365 days, we can cross simplify it so we only do interest/principle So 251.94799/1000 = 0.25194799 Which is about 25%

Tyannamj:

so that's the right one?

Tyannamj:

not the other ones?

snowflake0531:

That is APR ^^^^

snowflake0531:

For APY i ddint write all the steps but i wrote For example, you can calculate the rate to be 7%, and the periods per year tobe 4 times So, 7% interest 4 times a year, putting that into the equation it would be (1+(0.07/4))^4 -1 From ^^^ I get 0.07185903128, which is about 7.2% ig

Tyannamj:

then do you calculate the APY from that APR you did?

snowflake0531:

snowflake0531:

and i ss'ed the formulas in a couple of the above screenshots already

Tyannamj:

ok thank you sm

snowflake0531:

lel what grade are you in, what class is this for?

Tyannamj:

college algebra

snowflake0531:

never heard of that class b4 but k

snowflake0531:

huh, google says it's like algebra 2 but.... APR and APY is for like finance.... or something idk and bye xddd
