What does 1 dollar tripled every 2 days for 30 days equal?

Answer 1

And here we see that if a mathematical problem can be open to interpretation, it is possible to obtain vastly different results. Both experts agree that something gets tripled every two days, fifteen triplings in total. The first, showing the importance of compounding, posits that the first dollar gets tripled to three dollars after two days and that total gets tripled two days later, and subsequent totals etc.

The second thinks that a dollar gets tripled after two days and that process gets repeated.

The first solution is more likely the author's original intent, but it's important to state problems unambiguously.

Answer 2

(30 ÷ 2) × 3 = 45 dollars.

Answer 3

It is 4782969 dollars.
