Answer:

315881.53

Explanation:

We first need to figure out how long it takes for the money to triple

let x= number of years it takes for the money to tirple


3=(1+(.04)/(365))^(365x)\\log_(1.0001)3=365x\\10025.38644=365x\\27.46681216=x

Now plug that value into the continously compounding formula


80000*e^(27.4668*.05)=315881.5314

Which rounds to

315881.53
