1. A couple is contributing to a 529 plan (explained in the US Tax Code) for their two childrens college expenses. Assume they contribute $1800 per year to a fund that pays 6% interest annually. How much would they have in 10 years to help with college tuition? Assume the same couple above puts away $150 per month into the fund, also at 6% annual rate of return (or 0.5% monthly rate of return). What is the value of the account after 10 years, assuming there is monthly compounding?
