Life expectancy increases at a rate of (75.2-71.7)/4 = 3.5/4 = 0.875 yrs per yr.
E = 71.7 + 0.875 t
In 2004, t = 11 and E = 81.3
I doubt whether E can increase at that rate for very long, but that is what they want you to assume.
I am lost, and I bet it is simple, but I have been working with many problems and I keep coming back to this and I grow increasingly confused. How do I begin to solve this problem?
In 1993 the life expectancy of males in a certain country was 71.7 years. In 1997 it was 75.2 years. Let E represent the life expectancy in years t and let t represent the number of years since 1993
E(t)=_t+ _
Use the formula below to predict the life expectancy of males in 2004
E (14) =
