I'm completely lost with this math problem: Brendan makes $6/hour as a waiter. He's scheduled for 2 8-hour shifts and 1 12-hour shift this week. He also makes an average of $12 in tips each hour. Brendan is supposed to pay 20% of his income in taxes, but he only reports 1/3rd of his tips to the IRS. How much money does Brendan pay in taxes each week?
Can you give me a hand?
