conversations.value: Break down this math problem: Ariana is past due on three bills. The first bill for $200 charges 10% simple interest for each overdue month and it's 2 months overdue. The second bill for $130 charges a flat $50 late fee per month and is 6 months overdue. The last bill is two months late and charges a $40 fee the first month overdue and twice that fee the second month overdue and is for $444. How much does Ariana owe in total?

conversations.value: First find the monthly late fee for the first bill: $200 * 10% = $20
  Then multiply that by the number of months the bill is overdue: $20/month * 2 months = $40
  Then find the total late fee for the second bill the same way: $50/month * 6 months = $300
  Then find the third bill's second late fee: 2 * $40 = $80
  Then add all the bill amounts and late fees to find the total cost: $40 + $200 + $300 + $130 + $40 + $80 + $444 = $1234
