Tina made a large pan of brownies and cut it into 24 pieces.  She had one with lunch and dinner every day for 5 days.  Her husband snagged one per day for 5 days to take to work.  They shared 4 with dinner guests.  How many brownies were left?
Tina ate one twice a day for 5 days so 2*5 = <<1*2*5=10>>10
Her husband at 1 per day for 5 days so 1*5 = <<1*5=5>>5
She made 24, ate 10, her husband ate 5 and the guests ate 4 so 24-10-5-4 = <<24-10-5-4=5>>5 brownies left
