Answer:
It will depend on the interest rate; advise her to get a calculator.
Explanation:
The present value of the cash flows at a 5% and 9% discount rate are $2,859.41 and $2,759.11 respectively. The lump sum of $2900 is better because it is higher than the present values of the cash flows.
The decision to accept either the lump sum or the cash flows should depend on the interest rate.
If the present value of the cash flows discounted at the interest rate is greater than the lump sum, the cash flows should be accepted. If it isn't, the lump sum should be chosen.
