Answer:
The correct answer is $6,373.02.
We can use the formula for present value of an annuity:
PV = PMT x ((1 - (1 + r/n)^(-n*t)) / (r/n))
Where PV is the present value, PMT is the monthly payment, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.
Plugging in the values, we get:
PV = 300 x ((1 - (1 + 0.12/12)^(-12*2)) / (0.12/12))
PV = $6,373.02
Therefore, the present value of Maria's investment is $6,373.02.
