Solve the Problem $R = 5 e ^ { k x }$

Essay

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 $R = 5 e ^ { k x }$ where 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 (R = 10) 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?
