<span>n/2 = average number of items to search.
Or more precisely (n+1)/2
I could just assert that the answer is n/2, but instead I'll prove it. Since each item has the same probability of being searched for, I'll simulate performing n searches on a list of n items and then calculate the average length of the searches. So I'll have 1 search with a length of 1, another search looks at 2, next search is 3, and so forth and so on until I have the nth search looking at n items. The total number of items looked at for those n searches will be:
1 + 2 + 3 + 4 + ... + n
Now if you want to find the sum of numbers from 1 to n, the formula turns out to be n(n+1)/2
And of course, the average will be that sum divided by n. So we have (n(n+1)/2)/n = (n+1)/2 = n/2 + 1/2
Most people will ignore that constant figure of 1/2 and simply say that if you're doing a linear search of an unsorted list, on average, you'll have to look at half of the list.</span>

Calculation for the Insurance expense
Using this formula
Insurance expense= 2017 Ending Balance in prepaid insurance account+ Amount paid for insurance-2018 Ending Balance in prepaid insurance account
Let plug in the formula
Insurance expense=$68,400+$106,000-$42,000
Insurance expense=$132,400
Therefore the Insurance expense recorded 2018 would be $132,400

Answer:
Original price= $23,158.58
Explanation:
Giving the following information:
The company purchased a credit plan at Buy Right. Their monthly payments are $1,000 for 2 years. Buy Right will charge 3.45% per year compounded monthly.
First, we need to calculate the final value, using the following formula:
FV= {A*[(1+i)^n-1]}/i
A= monthly pay= 1,000
i= 0.0345/12= 0.002875
n= 12*2= 24
FV= {1,000*[(1.002875^24) - 1]}/ 0.002875
FV= $24,810.48
Now, we can calculate the original price:
PV= FV/(1+i)^n
PV= 24,810.48/ (1.002875^24)
PV= $23,158.58
