Question 602262: I apologize I am not sure if I chose the right subject.
I have been out of school for a while and I am rusty.
The formula is
S=a1/1-r
The problem is
a1=8 r=1/4
Please explain how to use the formula.
I believe S= 32 but I am pretty sure I am doing that wrong.
Thanks

The formula is
S= %28a1%29%2F%28%281-r%29%29
The problem is
a1=8 r=1/4
S= %288%29%2F%28%281-%281%2F4%29%29%29 = %288%29%2F%28%283%2F4%29%29%29 = 8 * 4%2F3 = 32%2F3
