    Have you seen y=a(1+b)^x where a=original amount b=growth rate(as decimal) x=time and y=amount at given time

    Well, it's not that hard to calculate use this calculator! For e^(...), press 2ND (blue button) then press LN. Does it help?

    Well, you can round it up to 89,973 since the question wants approximate number of attendance.

    68000(89972.82724)=6118152252 which is not in the answer chocies

    No, A = 89972.82724 since you have already multiplied e^(...) by 68000. You got about 6118152252 because you did it twice.

    Just calculate 68000 * e^(0.035 * 8)
