Heidi contributes 11% of her monthly salary towards her 401(k) and her employer matches her contribution up to 6% of her salary. If the interest rate of her 401(k) is 6.25% compounded monthly and her monthly salary is $3,250, determine the amount in her account after 15 years. Round to the nearest cent.

Heidi contributes 11% of $3,250, or $357.50 per month. Her employer adds a match of 6% of $3,250, which is $195, so the total monthly contribution is $552.50. Using the monthly rate 0.0625 ÷ 12 and 15 × 12 = 180 deposits, the future value of the monthly contributions is about $164,146.52. The best answer is $164,146.52.
