A young married couple is debating the value of a cell phone plan. The top of the line plan will cost them $300 per month with unlimited data and high end phones. The middle tier plan will cost $180 per month with enough features to keep them satisfied. Regardless of the plan chosen, the first payment will be made exactly in one month.

They will either purchase the top of the line plan or go with the middle tier option. If the couple goes with the middle tier plan, they will invest the savings each month in a mutual fund. The couple can earn 7.2% APR (with monthly compounding) on their investments in the market. What is the future value of these savings if the couple selects the middle tier plan and invests the savings each month for 40 years?
