Answer:
This is a constant problem. He kept on spending 1/3 of his money. The inverse number of 1/3 is 3. Basically the fraction flipped. So he spent 1/3 of his money 4 times. So we multiply 16*3*3*3*3. Multiply by 3 four times. 16*3 is 48. 48*3 is 144. 144*3 is 432. 432*3 is 1296. He started with 1296 dollars. If hes a kid hes rich.
