Sam invested $10,000 and earned 20% interest compounded for 3 years. He then invested more until he had three times as much invested. The next year, he got a 15% return on his investment. How much money does he have now?
Reason slowly and give your answer.
59616
After one year, Sam had $10,000 * 1.

2 = $12,000.

After two years, he had $12,000 * 1.

2 = $14,400.

After the third year, he had $14,400 * 1.

2 = $17,280.

He then invested more money until he had 3 * $17,280 = $51,840.

The first year after that, he had $51,840 * 1.

15 = $59,616.

.

So, the final answer is 59616
