Write the inequalities that describe the constraints on production.The Acme Class Ring Company designs and sells two types of rings: the VIP and the SST. The company can produce up to 84 rings each day, using up to 210 total man-hours of labor. It takes 3 man-hours to make one VIP ring and 7 man-hours to make one SST ring. Let x represent the number of VIP rings, and let y represent the number of SST rings.
A. 0 ? x ? 84, 0 ? y ? 84, 3x + 7y ? 210
B. x + y ? 84, 3x + 7y ? 210,

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?
