That would be (171 + x) / 2....what u do to find the average is add up all the numbers, then divide by how many numbers there are.
We start with
$1,187.92
With the interest and the late fee charge
$1,187.92 (1 + 0.1225/12) + 30 = $1,230.05
With the interest minus the payment of $125
$1,230.05 (1 + 0.1225/12) - $125 = $1,117.60
The new principal after the latest payment is $1,117.60.
The answer is 35/10 and 6/10
15/35
3/7 the answer is 3/7 which is written in the lowest terms
