Question

im stuck on this problem

Answer 1

i need steps

Answer 2

what i did a=68000e^(0.035*8)
68000e^(0.28)
now what?

Answer 3

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

Answer 4

no i havent i ssen A=pe^rt

Answer 5

What about \(\large A = P\left(1+\dfrac{r}{n}\right)^{nt}\)?

Answer 6

yeah i seen it but i have to use the one i told you about can you help me?

Answer 7

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

Answer 8

Ok, you are doing it right.

What kind of graphing calculator do you use?

Answer 9

TI-84 PLUS SILVER EDITION

Answer 10

Well, it's not that hard to calculate use this calculator!

For e^(...), press 2ND (blue button) then press LN.

Does it help?

Answer 11

okay i got 89972.82724 when i multiplied that by 68000 i got a strange answer

Answer 12

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

Answer 13

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

Answer 14

that doesnt change answer ?

Answer 15

No, A = 89972.82724 since you have already multiplied e^(...) by 68000.

You got about 6118152252 because you did it twice.

Answer 16

i dont understand whats the next steps after this

a=68000e^(0.035*8)
68000e^(0.28)

Answer 17

we found e what do we do with it?

Answer 18

Multiply it with 68000.

Answer 19

Exactly what don't you understand? Do you know what e is, right?

Answer 20

Just calculate 68000 * e^(0.035 * 8)

Answer 21

You got it?

Answer 22

ok so it 89973

Answer 23

Yes!

Answer 24

A=Pe^-rt
=26600e^(-0.29)
i put it in the calculator and got error

Answer 25
