Answer:
24.5
Step-by-step explanation:
first order the numbers from least to greatest
21 22 23 <u>24 25</u> 26 27 28
add 24 and 25 then divide them by 2
$15,920
The answer is - C. R & W
f(n) = 100·4^(n-1)
The given function c(n) is apparently the multiplier for n days. Its value is 1 for n=1, so we simply need to multiply c(n) by 100:
f(n) = 100·c(n) = 100·4^(n-1)
