Question

\according to the rule of 72, if beth invests $200 and $1300 into two separate accounts with the same interest rate, which amount will double faster?

Answer 1

At the same interest, both amounts will double at the same rate.

To understand this, consider a 5% interest rate:
5% of 200 is 10 so it will take 20 years for 200$ to be doubled
5% of 1300 is 65 so it will also take 20 years for 1300$ to be doubled

Answer 2

Answer:

both will double at the same rate
