Answer:
13. 23 boat rides; 22 are full, and the first one has 301 passengers.
12. $11,067.50
<span>Data:
infinite geometric series
A1
= 880
r = 1 / 4
The sum of a geometric series in sigma
notation is:
n 1 - r^n
∑ Ai = A ----------- ; where A = A1
i = 1 1-r
When | r | < 1 the infinite sum exists and is equal to</span><span><span>:
∞ A
∑ Ai = ---------- ; where A = A1
i = 1 1 - r</span>
So, in this case</span><span><span>:
∞ 880
∑ Ai = -------------- = 4 * 880 / 3 = 3520 /3 = 1173 + 1/3
i = 1 1 - (1/4)</span> </span>
Answer: 1173 and 1/3
Using the denominator of 3 we know 3/3 would be equal to 1
Subtract 3/3 from 4/3 = 1/3
So 4/3 = 1 and 1/3
The answer is c.
