Q$5.$ In the sheet Q$5$ you will find a partially$-$filled worksheet. A young married couple has carefully looked at their budget. After review, they can afford a monthly mortgage payment of $$1,000.$ They go to their local banker and she offers them a mortgage of $8\mathrm{.}5\%$ APR with monthly compounding over a term of $30$ years.
