Emanuel has -$1,000 in his bank account. He
deposits $100 each month he gets paid for
walking dogs. After some time, he notices his
account balance is now at $0. How many
months has it been?
Because he was at $-1,000 and he deposited $100 a month that he earns from watching the dogs so it took him 10 months to realize that his bank account is now at $0
