Steel cable barriers in highway medians are a low-cost way to improve traffic safety without busting state department of transportation budgets. Cable barriers cost $44,000 per mile, compared with $72,000 per mile for guardrail and $419,000 per mile for concrete barriers. Furthermore, cable bar-riers tend to snag tractor-trailer rigs, keeping them from ricocheting back into same-direction traffic. The state of Ohio spent $4.97 million installing 113 miles of cable barriers. a. If the cable prevents accidents totalling 1.3 million per year determine the rate of return that this represents over a ten year study period. Use all three methods tabulated factors a calculator, and spreadsheets.
b. Now determine the rate of return for 113 miles of guardrail if if accident prevention is 1.1 million per year over a period of 10 year. To do so first write the ROR relation and then find I* using a single cell spreadsheet function.

1   all nations face the problem of scarcity because there are limited resources and unlimited wants. nations do not have enough factors of production to produce everything that their population wants. entrepreneurial resources initiate businesses to make new goods and services; labor resources produce goods and services.
