Posting this again because no one answered

A rumor that was told initially to three people is spreading at a rate of 5% each week. The following function represents the weekly spread of the rumor: f(x) = 3(1.05)x. Rewrite the function to show how quickly the rumor spreads each day and calculate this rate as a percentage.


A) f(x) = 3(1.007)7x; spreads at a rate of approximately 0.7% daily

B) f(x) = 3(1.05)7x; spreads at a rate of approximately 0.5% daily

C) f(x) = 3(0.15)x; spreads at a rate of approximately 0.15% daily

D) f(x) = 3(1.007)x; spreads at a rate of approximately 0.07% daily

Answer 1

The Answer is DEFINITELY NOT D, its C

Explanation:

I did the Flvs test a second ago and picked D, guess what I got the question wrong, its C

Answer 2

I think D would make the most sense here

Explanation:

If it's spreading 5% each week, that means it has to be a smaller amount each day... like it couldn't spread 15% in a day because that's already over 5% for the whole week
