Jordan is a great kid, and he works very hard at his favorite sport: basketball. He gets average grades at school because he spends a lot of his after-school time hanging out with friends and playing video games instead of doing homework. He earns money for doing lawn work and spends every nickel on new video games and eating out with friends. Jordan is about to graduate from high school, and his uncle is going to deposit money in an account for Jordan's future. "In 10 years, you'll need this money," he tells Jordan.

Jenny​ walters, who owns a real estate​ agency, bought an old house to use as her business office. she found that the ceiling was poorly insulated and that the heat loss could be cut significantly if six inches of foam insulation were installed. she estimated that with the​ insulation, she could cut the heating bill by​ $80 per month and the​ air-conditioning cost by​ $70 per month. assuming that the summer season is three months​ (june, july, and​ august) of the year and that the winter season is another three months​ (december, january, and​ february) of the​ year, how much can jenny spend on insulation if she expects to keep the property for five​ years? assume that neither heating nor​ air-conditioning would be required during the fall and spring seasons. if she decides to install the​ insulation, it will be done at the beginning of may.​ jenny's interest rate is​ 6% compounded monthly.
