Question: Siri spent a quarter of her babysitting money on a new pair of sunglasses. If she makes $9.50 per hour and babysat for 8 hours, how much money did she have left after buying the sunglasses?

Answer: $57.00

Solution: Siri worked for 8 hours earning $9.50/hour for a total of 8 x $9.50 = $76.00. She spent a quarter of that money, which is half of half of 76 = half of 38 = $19.00 on sunglasses. Siri was left with $76.00 - $19.00 = $57.00 a fter buying sunglasses.
