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

no i havent i ssen A=pe^rt
geerky42
  • geerky42
What about \(\large A = P\left(1+\dfrac{r}{n}\right)^{nt}\)?

i have a graphing caculator i just dont know what to do next and with e

TI-84 PLUS SILVER EDITION

  • geerky42
Well, it's not that hard to calculate use this calculator! For e^(...), press 2ND (blue button) then press LN. Does it help?

okay i got 89972.82724 when i multiplied that by 68000 i got a strange answer
geerky42
  • geerky42
Well, you can round it up to 89,973 since the question wants approximate number of attendance.

  • anonymous
68000(89972.82724)=6118152252 which is not in the answer chocies
anonymous
  • anonymous
that doesnt change answer ?
geerky42
  • geerky42
No, A = 89972.82724 since you have already multiplied e^(...) by 68000. You got about 6118152252 because you did it twice.

i dont understand whats the next steps after this a=68000e^(0.035*8) 68000e^(0.28)
anonymous
  • anonymous
we found e what do we do with it?
geerky42
  • geerky42
Multiply it with 68000.
geerky42
  • geerky42
Exactly what don't you understand? Do you know what e is, right?
geerky42
  • geerky42
Just calculate 68000 * e^(0.035 * 8)
geerky42
  • geerky42
You got it?
anonymous
  • anonymous
ok so it 89973
geerky42
  • geerky42
Yes!

A=Pe^-rt =26600e^(-0.29) i put it in the calculator and got error
geerky42
  • geerky42
That's strange, I put it in the calculator and I didn't get error...
