Question

according to the rule of 72 if Beth invest $200 and $1300 into two separate accounts with the same interest rate which amount will double faster

Answer 1

Answer: They will both double at the same rate.

Step-by-step explanation: Imagine you have a 10% interest rate:

10% of 200 is 20 so it will take 10 years for 200$ to be doubled.

10% of 1300 is 130 so it will take 10 years for 1300$ to be doubled.
