Question

OpenStudy user r94 posted a picture of a 28 year old man. She stopped increasing fans and people started to unfan her. She started losing 1% of her fans everyday compounded.
After 6 days, she noticed that her fan count is lost, so she posts a duckface and starts gaining 5% of her fan count everyday - compounded.

Assume that r94 started at 250 fans. How many fans are there by 40 days?

Answer 1

Too many to count.

Answer 2

xP

Answer 3

Can you solve this, becca?

Answer 4

No. I'm too stupid. ;D

Answer 5

This would include the continuous compounding - Original(1 + increase rate)^n

Answer 6

the what?

Answer 7

Lol I made the post funnier

Answer 8

Is the answer at the very end 349??

Answer 9

xD

Answer 10

lol

Answer 11

\( \color{Black}{\Rightarrow250(1 - 0.01)^6 }\)

\( \color{Black}{\Rightarrow 250(0.99)^6 }\)

\( \color{Black}{\Rightarrow 234 }\)

Answer 12

but I has more than that :( I have failed

Answer 13

Now calculate the remaining days:

\( \color{Black}{\Rightarrow 234(1 + 0.05)^{36} }\)

Answer 14

That was gonna be my second guess.

Answer 15

\( \color{Black}{\Rightarrow 234(1.05) }\)

\( \color{Black}{\Rightarrow 234 \cdot 5.8 }\)

\( \color{Black}{\Rightarrow 1357.2 }\)
