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 = 5ekxwhere x is the variable concentration of alcohol in the blood and k is a constant.Suppose that a concentration of alcohol in the blood of 0.07 results in a 10% risk 
of an accident. Find the constant k in the equation.Using this value of k, what is the risk if the concentration is 0.11?
What will be an ideal response?
k = 
? 9.90; about 14.9%
