Based on the available information, and the options provided, the answer is option A. No, $8,816.47 is not enough to cover the cost of 2 years at a 2-year public institution. Without earning interest, it would take Christian approximately 4 years and 4 months to save up $8,816.47.
This is because to cover the cost of 2 years at a 2-year public institution, Christian would need to save $3,900 per year, as stated in the question. Over a 4-year period, the total cost would be $7,800 ($3,900 x 2 years).
However, Christian's savings, with an investment account that has a 3.75% annual interest rate compounded monthly, would accumulate to $8,816.47 over the same 4-year period. This amount is higher than the cost of 2 years at a 2-year public institution.
If Christian were to save the money without gaining any interest, it would take him approximately 4 years and 4 months to reach $8,816.47. This means that even without earning any interest, Christian would still be able to save enough to cover the cost of 2 years at a 2-year public institution.
