Given the following information for a one-year project, answer the following questions. • planned value (pv) = $30,000 • earned value (ev) = $27,000 • actual cost (ac) = $25,000 • budget at completion (bac) = $150,000 1. what is the cost variance, schedule variance, cost performance index, and schedule performance index for the project? 2. is the project ahead of schedule or behind schedule? 3. is the project under budget or over budget? 4. use the cost performance index to calculate the estimate at completion (eac) for this project. is the project performing better or worse than planned? 5. use the schedule performance index to estimate how long it will take to finish this project.

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.
