Question

In 1995 the life expectancy for a female born in the United States was 75.9 years, and was increasing at a rate of 0.23 years per year. Assuming this rate of increase remains constant, what will the life expectancy of a female born in the U.S. in 2005 be?

Answer 1

78.2 years

2005 - 1995 = 10
.23 * 10 = 2.3
75.9 + 2.3 = 78.2
