Solve the problem.The rates of death (in number of deaths per 100,000 population) for 1-4 year olds in a certain country between 1995-2010 are given below. 
A logarithmic equation that models this data is y = 822.99 - 167.55 ln x where x represents the number of years since 1915. Use this equation to predict the rate of death for 1-4 year olds in 2020. Round to the nearest tenth.
A. 50.3 deaths per 100,000
B. 39.2 deaths per 100,000
C. 43.2 deaths per 100,000
