Solve the problem.The concentration of alcohol in a person's blood is measurable. Suppose that the risk R (given as a percent) of having an accident while driving a car can be modeled by the equation R = 7ekxwhere x is the variable concentration of alcohol in the blood and k is a constant.(a) Suppose that a concentration of alcohol in the blood of 0.08 results in a 13% risk 
of an accident. Find the constant k in the equation.(b) Using this value of k, what is the risk if the concentration is 0.013?(c) Using the same value of k, what concentration of alcohol corresponds to a risk of 100%?(d) If the law asserts that anyone with a risk of having an accident of 12 or
more should not have driving privileges, at what concentration of alcohol in the blood should a driver be arrested and charged with a DUI? What will be an ideal response?
