Question

Someone Please Help Me!!!
Determine the fraction of total interest owed.

After the seventh month of a 12-month loan,

the numerator is: {(n + 11) + (n + 10) + (n + 9) + (n + 8) + (n + 7) + (n + 6) + (n + 5)} = (a)64, (b)65, (c)63, and
the denominator is: {(n) + (n + 1) + ... + (n + 11)} = (a)76, (b)77, (c)78.

Therefore, the fraction is numerator/denominator (to the nearest tenth) =(a)8.1%, (b)80.8%.
