The sum of the 18 numbers is 22.5 x 18 = 405.
Let the numbers be x, x + 1, x + 2, . . ., x + 17
Sum of n term of an arithmetic sequence = n/2(a + l)
18/2(x + x + 17) = 405
9(2x + 17) = 405
2x + 17 = 405/9 = 45
2x = 45 - 17 = 28
x = 28/2 = 14
Therefore, the smallest integer is 14.

We have to compute first for the total cost of the loan by obtaining the monthly amortization:
<span> A= P/ [(1+ r/n)^n-1] /r(1+r/n)^n</span>
where
P= loan amount
P= $35125
r=interest rate of 7.44%
n = compounding frequency of 4
t= length of loan 10 years
A= $1252.7
Total cost = $1252.7x40=$50108
Computing the percentage of the finance charges
Finance charge = debt charge+service charge
Finance charge% =($50108-$32125+$5180.7)($50108+$5180.7)x 100
=36.47%
The answer is letter b.36.47%

Step-by-step explanation:
7+100+1+3+7+10+15+12+17+38/10
The mean of the third sample is 21.
Y - the money he still owes,
x - the number of months ( from x = 0 to x = 18 ):
y = 2,016 - 112 x
