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
= 
( a is the first term )
= 
= 50 × 255 = 12750
Answer: 22 hours 11 minutes
<u>Step-by-step explanation:</u>

x=75 miles
hope this helps
Only the first choice is correct.
sorry about my previous comments; they were from misunderstanding.
Answer:
The capacity of smaller cooler = 7.5 gallons
The capacity of bigger cooler = 37.5 gallons
Step-by-step explanation:
Let smaller cooler's capacity be x gallons
Hence
Larger cooler's capacity will be 5x gallons
Together, they will hold 45 gallons, thus we can write:
x + 5x = 45
Solving:
x + 5x = 45
6x = 45
x = 45/6 = 7.5
And 5x = 5(7.5) = 37.5
The capacity of smaller cooler = 7.5 gallons
The capacity of bigger cooler = 37.5 gallons
