Answer:
85%
Explanation:
The calculation of return on investment is shown below:-
For calculating the return on investment first we need to find out the immediate return which is shown below:-
Immediate return = Tax savings + Employer matching contribution
= ($2,000 × 35%) + ($2,000 × 50%)
= $700 + $1,000
= $1,700
Now, we will compute the return on investment
Return on investment = Immediate return ÷ Amount invested by Joannie
= $1,700 ÷ $2,000
= 0.85
or
= 85%
So, for computing the return on investment we simply divide the immediate return by amount invested by Joannie.
