Answer: The required average is $576.
Step-by-step explanation:
Since we have given that
Percent of customers not returning each year = 25%
Average customer lifetime = 
Percent of margin on the average bill = 60%
Cost per visit = $12
Number of times each year visited = 20 times
So, Average expense by each customer per year =

Step-by-step explanation:
There are two ways in
finding the place value of 2 in 5,670,249,114
First by breaking down the numbers:
5,670,249,114 = 5,000,000,000 +
600,000,000 + 70,000,000 + 200,000
+ 40, 000 + 9,000 + 100 + 10 + 4
which means the Value of 2
is 200, 000<span>2. Second, by using the ones words:
5,670,249,114 = 5 billion + 6 hundred million + 70 ten million + 2 hundred thousand + 4 ten thousand + 9
thousands + 1 hundreds + 1 tens + 4 ones
which means the Value of 2 is 2
hundred thousand
