Answer:
12750
Step-by-step explanation:
The sequence of visitors is
50, 100, 200, 400, .....
This is a geometric sequence
with common ratio r = 2
The sum to n terms is found using
[tex]S_{n}[/tex] = [tex]\frac{a(r^n-1)}{r-1}[/tex] ( a is the first term )
[tex]S_{8}[/tex] = [tex]\frac{50(2^8-1}{2-1}[/tex] = 50 × 255 = 12750
