Ricky Dong went offline shopping. A lot of people were online so he could buy more things since there were not a lot of people offline. He had a budget of -3000 dollars that his pet Uncle Joe gave him. He bought exactly four things. He bought a chicken, which was $20.00, he bought a 7-year-old kid for $50.36, he bought someone's house for $2.45, and lastly, he bought his Uncle Joe some flop flips, which were $-20.56. So, Ricky Dong thinks the total money he has left is $600.74, but his Uncle Joe says he has $2.78. Who is right? If they are both wrong, explain why and give the right answer. PLEASE HELP QUICK!
