Solve the problem.The rates of death (in number of deaths per 100,000 population) for 20-24 year olds in the United States between 1985-1993 are given below. (Source: NCHS Data Warehouse) A logarithmic equation that models this data is y = 57.76 + 48.56 ln x where x represents the number of years since 1980 and y represents the rate of death in that year. Use this equation to predict the year in which the rate of death for 20-24 year olds first exceeds 200.

Fill in the blank(s) with the appropriate word(s).
