Mind telling me If I got this right?
An amount of $49,000 is borrowed for 13years at 7.5% interest, compounded annually. If the loan is paid in full at the end of that period, how much must be paid back?Use the calculator provided and round your answer to the nearest dollar.
f=49000(1+0.075)^13 =1254602.40378726
or
f=49000(1-0.075)^13= 177843.74932331

"A" is what you need to find.

yea and i already found them but i need to know which one is right.

- SolomonZelman

I have a wierd glitch, don't know why.

- SolomonZelman

that one

- teller

Thank you so how do i round it ?

- SolomonZelman

did you find the value?

- teller

1254602.40378726 is what i got i just need to know how to round it now.

- phi

when you owe interest, it is added to the total cost. the final amount will be more than what you borrowed. that is how to remember (1+r) (and not (1-r) )

- SolomonZelman

well, the amount you will have to return is 125460.24

- teller

It has to be rounded.

- SolomonZelman

well rounded to nearest cent.

- teller

it said dollar...

- teller

that's what i need help with.

- SolomonZelman

Well:
31, 32, 33, 34 would round up to 30
35, 36, 37, 38, 39 would round up to 40

- SolomonZelman

So from 5 to 9, rounds up.
And from 1 to 4, rounds down

- teller

1254602.3?

- SolomonZelman

you keep missplacing the point

- SolomonZelman

decimal is after the 0

- SolomonZelman

And you have
125460.\(\color{red}{2}\)4
and 60.\(\color{red}{2}\) would round to 61.0 or 60.0 ?

- teller

so the answer is 125460.24?

- SolomonZelman

well, you want to round to nearest dollar, so then not.

- teller

dude what the hell?You keep telling me 125460.24

- teller

all your doing is confusing me even more.

- SolomonZelman

125460.24
is the answer with cents.

- SolomonZelman

They ask you to round that up to dollar

- teller

HOW !?!?

- teller

i've been asking you for the last 5 minutes how?

- teller

not asking for cents it's asking for dollars.

- SolomonZelman

60.2
where would the 2 round it to? UP (and you have 61.0) or DOWN (and you have 60.0).
-----------------------------------
Recall that:
31, 32, 33, 34 would round up to 30
35, 36, 37, 38, 39 would round up to 40

- SolomonZelman

"Recall that" and below is an example

- teller

125461.24?

- SolomonZelman

125460.24 ---> 125460.00

- teller

so the answer is 125460.00?

- SolomonZelman

yes
