Answer:
512
Solution:
so first you multiply 15 times 32 and get 480 than you add 32 and get 512.

A=84 and r=1/5
Since r, the common ratio squared is less than one, the sum will converge to a limit. Rule: if r^2<1 infinite series converges, otherwise it diverges.
Since the sum of any geometric sequence is:
s(n)=a(1-r^n)/(1-r)
And if r^2<1, (1-r^n) becomes 1-0=1 as n approaches infinity.
So whenever r^2<1 the sum of the infinite series is just:
s(n)=a/(1-r)
Since a=84 and r=1/5 this infinite series has a sum of:
s(n)=84/(1-1/5)
s(n)=84/(4/5)
s(n)=5(84)/4
s(n)=105
Answer:
$12.89
Step-by-step explanation:
3.23 lb × 3.99 $/lb = 12.8877 $
Since we have to round to the nearest cent, Sanaa should collect $12.89.
