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) \(0.28\)
Dogs need \(8.5\) to 17 ounces of water each day for every 10 pounds of their weight. Everett has two dogs - Ringo is a 35-pound black lab mix, and Elvis is a 55-pound beagle. Which of the following ranges represents the approximate total number of ounces of water, \(w\), that Elvis and Ringo need in a week? A) \(77 \leq w \leq 153\) B) \(109 \leq w \leq 218\) C) \(536 \leq w \leq 1,071\) D) \(765 \leq w \leq 1,530\)
The number of bonus points, \(B(p)\), that a credit card holder receives is given by the function \(B(p)=4 p+7\), where \(p\) represents the number of purchases made. If the number of purchases is increased by 3 , by how much does the number of bonus points increase? A) 3 B) 4 C) 12 D) 19
The population, \(P\), of Town \(Y\) since 1995 can be estimated by the equation \(P=1.0635 x+3,250\), where \(x\) is the number of years since 1995 and \(0 \leq x \leq 20\). In the context of this equation, what does the number \(1.0635\) most likely represent? A) The estimated population of town \(Y\) in 1995 B) The estimated population of town \(Y\) in 2015 C) The factor by which the population of town \(Y\) increased yearly D) The factor by which the population of town \(Y\) decreased yearly
