Lizzy: Jacoby wants to save money for a trip to Brickville. He needs to have $5000 total to go on his trip. He works a job earning $20 per hour and works 10 hours. He then finds he can sell cookies for $4 each, and he sells 24 pieces of cookies. With the money he has so far, he buys a lottery ticket for $10 and wins $500. Finally, he gets $500 from both of his sisters as a gift. How much more, in dollars, does Jacob need to go to Brickville?.
Me: Hmmm, let me think. I think this is the detailed solution:
Jacob earns $20 per hour * 10 hours = $200 for working. So he earns $4 each * 24 = $96 for the cookies. So far he has earned $200 + $96 = $296. He buys a lottery ticket so $296 - $10 = $286 was left in his money. After winning in a lottery, he had a total of $500 + $286 = $786. He gets $500 * 2 per sister = $1000 from her sisters. So he has so far $1000 + $786 = $1786. He needs $5000 - $1786 = $3214. Final answer: 3214.
