The component’s purchase price, $0.90, compared favorably with the standard price of $1.10. Given the quantity that would be purchased, Pat knew that the favorable price variance would help to offset an unfavorable variance for another component. By offsetting the unfavorable variance, his overall performance report would be impressive and good enough to help him qualify for the annual bonus. More importantly, a good performance rating this year would help him to secure a position at division headquarters at a significant salary increase. Purchase of the part, however, presented Pat with a dilemma. Consistent with his past behavior, Pat made inquiries regarding the reliability of the new supplier and the part’s quality. Reports were basically negative. The supplier had a reputation for making the first two or three deliveries on…arrow_forward

- When the country’s economy is expanding, AB Investment Company is optimistic and expects a MARR of 15% on new investments. However, in a receding economy the expected return is 8%. Normally a 10% per year return is anticipated. An expanding economy causes the estimates of project life to go down about 20%, and a receding economy causes the life values to increase about 10%. Additionally, the market value after the project’s life varies widely; optimistically, it may be as high as 50% more or as low as 75% of the initial investment. (a) Summarize the optimistic, most likely, and pessimistic estimates in tabular form. (b) Use a spreadsheet to calculate and plot the sensitivity of PW versus (1) MARR, (2) life values, and (3) market value for possible investment in one of two locations.
