on simple intrest?

Question

simple intrest 8%
original principal and intrest was $7560
how much did he originally invest

Answer 1

guessing it was in for only a year
7560=x(1+.08)
7560/1.08=x
x=7000

Answer 2

The original investment + one year's simple interest = $7560.

So 108% = $7560

So 100% = (7560/108) x 100 = $7000

So, the original investment was $7000.

Check this by calculating 8% of 7000. That is 7000 x 0.08 which = 560. Then 7000 + 560 = 7560 as expected.

Answer 3

How many years?
If it is one year, and the intrest is 8%, then the principal plus intrest is 108%, so you divide 7560 by 1.08 to get 7000. $7000 is the amount of money that he originally invested.

Answer 4

Al spectacular permit's try this. elementary interest is PxRxT=I to try this subject you're able to take the unique thought plus the interest to get the recent volume (7000). P + I = 7000 P + (PxRxT) = 7000 (We only subsituted the formulation for interest for the I.) putting interior the numbers P+(Px.09x.5)=7000 the fee is .09 (9% positioned into decimal) and the time is a million/2 year (6/12) P+(Px.0.5)=7000 a million.045P=7000 P=7000/a million.0.5 P=6698.fifty six we are able to verify with the aid of putting the P into the unique formulation and looking out I (it rather is 301.40 3) and including that returned to P we discover we've 6999.ninety 9. the single penny went to rounding. In math it rather is the excellent suited answer. Philosophically you could argue you definitely choose 6698.fifty seven via fact that the different huge style leaves you a penny short. on the different hand maybe banks do no longer around (which they do). positioned down the $6698.fifty six, yet then ask at college in case you mustn't in all risk put in a penny extra as or you're short a penny on the top. in the adventure that your in college your instructor might provide you factors for insightfullness. If in severe college you're extra in all risk to have the instructor think of you're a wiseas*.

Answer 5

You did n't say how long it was invested for. I'll do it for 1 year.
I = PRT/100

so P = 100 I/RT

P = 100 x 7560/ 8x1

P = $ 94,500

Ratty et al..please tell me where you can get $7560 interest on a
$7000 investment in a year...I'll be there like a shot!!!
Think about it people..it's impossible!!!
You can't get more interest than you put in!!!
The interest you use is $560 not $7560.

Answer 6

The question is incomplete, but if it was only for a year the first answer is absolutely correct. $7,000
