we are given
past due balance is $87.50
new charges is $75.00
a late fee of 15% of my past due balance
now, we can find late fee
late fee = 15% * 87.50
late fee=13.125
now, we can find new total
new total = due balance + new charges + late fee
new total = 87.50+75+13.125
so,
new total is $175.625..........Answer
