A construction firm needs a new small loader. It can be purchased for $20,000. The firm expects the loader to have a salvage value of $6,000 after 7 years. The maintenance cost will be $1,400 each year. The firm's interest rate is 6% per year. Compute the Equivalent Uniform Annual Worth (EUAW). EUAW = EUAB - EUAC Submit the absolute value of your answer (positive value). Margin of error: +/- 50 1 A college student has been looking for a new tires. The student feels that the warranty period is a good estimate of the tire life and that 10% interest rate is appropriate. Given 4 options find the minimum Equivalent Uniform Monthly Cost.
