if your one-penny allowance doubles every day for 30 days, how much is the allowance on the 30th day?

Question

i need the equation.

Answer 1

Let n = equal the number of days, and a = your allowance.

a = 2^n, because you're multiplying by 2 every day. On day 30, you're essentially multiplying 2 30 times.

a = 2^30 = $10,737,418.24
