What nominal interest rate per year is equivalent to 11.5% per year, compounded monthly?

If you are able to save $5000 in year 1,$5150 in year 2, and amounts increasing by 3% each year through year 20, the amount you will have at the end of year 20 at 10% per year interest is closest to: (a) $60,810 (b)$102,250 (c) $351,500 (d) Over$410,000

Revenue into the general fund of the state of Texas for any biennium is highly dependent on the price of oil. At a price average of $50 per barrel, general revenue will be$95 billion. At $68 and$75 per barrel, the revenue will be $118 billion and$125 billion, respectively. If the chances are estimated at 10%, 35%, and 55% for oil prices of $50,$68, and $75 per barrel for the next biennium, respectively, the expected revenue (in$ billion) is closest to: (a) $117.38 (b)$118.02 (c) $118.92 (d)$119.50

An alumnus of West Virginia University wishes to start an endowment that will provide scholarship money of $40,000 per year beginning in year 5 and continuing indefinitely. The donor plans to give money now and for each of the next 2 years. If the size of each donation is exactly the same, the amount that must be donated each year at i = 8% per year is closest to: (a)$190,820 (b) $122,280 (c)$127,460 (d) $132,040

The initial cost of a packed-bed degassing reactor for removing trihalomethanes from potable water is $84,000. The annual operating cost for power, site maintenance, etc. is$13,000. If the salvage value of the pumps, blowers, and control systems is expected to be $9000 at the end of 10 years, the AW of the packed-bed reactor, at an interest rate of 8$−26,140 (b) $−25,518 (c)$−24,900 (d) $−13,140

Four mutually exclusive alternatives are evaluated using three estimates or strategies (pessimistic, most likely, and optimistic) for several parameters. The resulting PW values over the LCM are determined as shown. $$ \begin{array}{lcccc} & & \text { PW of Alternative, } \$ \\ \text { Strategy }& \hline 1 & 2 & 3 & 4 \\ \hline \text { Pessimistic (P) } & 4,500 & -6,000 & 3,700 & -1,900 \\ \text { Most likely (ML) } & 6,000 & -500 & 5,000 & -100 \\ \text { Optimistic (O) } & 9,500 & 2,000 & 10,000 & 3,500 \\ \hline \end{array} $$ If none of the strategies is more likely than any other strategy, the alternative to select is: (a) 1 (b) 1 and 2 are equally acceptable (c) 2 (d) 3
