Jen had $9 before lunch. He spent half of it, or $4.50, on lunch. He then spent $1.50 for a magazine, leaving him with $2.50. One third of $2.50 is $0.83, which he used to pay for the bus ride home. He then gave his little brother a quarter, leaving him with three nickles and two quarters. $4.50 + $1.50 + $0.83 + $0.25 = $6.08 Jen had $9 before lunch, so $9 - $6.08 = $2.92.
