(b) Hodgkiss Mfg., Incorporated, is currently operating at only 88 percent of fixed asset capacity. Fixed assets are $354,200. Current sales are $460,000 and projected to grow to $575,000. How much in new fixed assets are required to support this growth in sales? Assume the company wants to operate at full capacity.

Retirement Investment Advisors, Incorporated, has just offered you an annual interest rate of 4.2 percent until you retire in 40 years. You believe that interest rates will increase over the next year and you would be offered 4.8 percent per year one year from today. If you plan to deposit $12,000 into the account either this year or next year, how much more will you have when you retire if you wait one year to make your deposit?
