Please help me If you get it right or really close I will post FREE points! Malcolm borrowed $550 from his parents to buy a used computer. He did not have to pay them back for the first four months, but starting on the fifth months, he began paying them back at $50 per month until the loan was paid off.

Trish bought a $650 computer at the same time. She got a loan from the computer store for the full amount of the loan. At the beginning of every month, starting the month after she bought the computer, she pays 10% of the remaining balance.

After month 2, Trish owes less on her computer than Malcolm does. After how many total months (including the first 2) will Malcolm owe less than Trish?

Round your answer to the whole month if necessary.
