Since we have given that
![A(t)=424(1+0.06)^t](https://img.qammunity.org/2020/formulas/mathematics/high-school/tominkg070m39j2nawro86k8cbcqji7dy1.png)
Since it is the formula for Compound interest,
Here, Principal amount = $424
Rate of growth = 6%
Number of years = t years
Hence, Stephanie originally invest $424, where interest is compounded every year.
