Your child is planning attend summer camp for three months, starting 7 months from now. The cost for camp is $1,000 per month, each month, for the three months she will attend. If your investments earn 5% APR (compounded monthly), how much must you invest each month, starting next month, for 3 months such that your investment will grow to just cover the cost of the camp?
