The table above shows the relative investment in alternative energy sources in the United States by type. One column shows the relative investment in 2007 of $$\$75$$ million total invested in alternative energy. The other column shows the projected relative investment in 2017 given current trends. The total projected investment in alternative energy in 2017 is $$\$ 254$$ million. Suppose that a new source of alternative energy, Cold Fusion, is perfected. It is projected that by 2017 that $$\$ 57$$ million will be invested in Cold Fusion in the United States, without any corresponding reduction in investment for any other form of alternative energy. What portion of the total investment of alternative energy in the United States will be spent on biofuels? A) \(0.18\) B) \(0.22\) C) \(0.28\)
If \(\left(i^{413}\right)\left(i^x\right)=1\), then what is one possible value of \(x\) ? A) 0 B) 1 C) 2 D) 3
Melanie puts $$\$ 1,100$$ in an investment account that she expects will make \(5 \%\) interest for each three-month period. However, after a year she realizes she was wrong about the interest rate and she has $$\$ 50$$ less than she expected. Assuming the interest rate the account earns is constant, which of the following equations expresses the total amount of money, \(x\), she will have after \(t\) years using the actual rate? A) \(x=1,100(1.04)^{4 t}\) B) \(x=1,100(1.05)^{4 t-50}\) C) \(x=1,100(1.04)^{t / 3}\) D) \(x=1,100(1.035)^{4 t}\)
