Question: Alice and Bob are each given $2000 to invest. Alice puts all of her money in the stock market and doubles her money. Bob invests in real estate and makes five times more money than he invested. How much more money does Bob have now than Alice?
Solution:
When Alice invested her money in the stock market, her money doubled to $2000*2 = $4000
Bob, after investing in real estate, increased his money by 2000*5 = 10000
The total amount of money that Bob made after investing in real estate is $10000+$2000 = $12000
Bob made $12000-$4000 = $8000 more than Alice after investing his money.
Answer: 8000
