You remember it because they are 6 and 7 or 9 and 8 have something together and that's how you remember it                                                           9x6=54                                                                                                                8x7=56                                                   
and also you just need to add 2+54=56

so that's all you real need to know about it

So 9x6 and 8x7 if you do 9x7 it's 54 and all you just need to do is add 2

On your tenth birthday, you received 500 which you invested at 9.5% interest, compounded annually. your investment is worth $250
igomit [66]
Compounded once a year: A=P(1+r)^t
2500=500(1+0.095)^t
1.095^t=5
because the unknown number is an exponent, use log to find the unknown:
log(1.095^t)=log5
tlog1.095=log5
t=log5/log1.095
use your calculator, t=17.734
so this person is about 28 years old.
