Question

Isabella saved 2 nickels today. If she doubles

the number of nickels she saves each day, how
many days, including today, will it take her to
save more than 500 nickels?

Answer 1

500 = 2^(2x)
I think something like that.

Answer 2

Answer: It will take her 125 days to save 500, so technically 126 to save more than 500

Explanation:

500/4
