Solve the Problem $\mathrm{f}(\mathrm{x})=11.1 \mathrm{x}+215$ , Where $\mathrm{x}$ Represents the Number of Years After 1995

Multiple Choice

Solve the problem.
-The number of male lawyers, in thousands, in a certain country in a particular year can be approximated by the function $\mathrm{f}(\mathrm{x}) =11.1 \mathrm{x}+215$ , where $\mathrm{x}$ represents the number of years after 1995. The number of female lawyers, in thousands, in a certain country in a particular year can be approximated by the function $\mathrm{g}(\mathrm{x}) =10.1 \mathrm{x}+143$ , where again $\mathrm{x}$ represents the number of years after 1995.
(i) Find $(f+g) (x)$ . Explain, in your own words, what this function represents.
(ii) Find $(f+g) (45)$ . Explain, in your own words, what this number represents.

A) (i) $(\mathrm{f}+\mathrm{g}) (\mathrm{x}) =154.1 \mathrm{x}+225.1$ ; this is the total number of lawyers, in thousands, in a certain country x years after 1995 .
(ii) 7159.6; there will be 7,159,600 lawyers in a certain country in the year 2040.
B) (i) $(\mathrm{f}+\mathrm{g}) (\mathrm{x}) =379.2 \mathrm{x}$ ; this is the total number of lawyers, in thousands, in a certain country $\mathrm{x}$ years after 1995.
(ii) 17,064; there will be 17,064,000 lawyers in a certain country in the year 2040.
C) (i) $(\mathrm{f}+\mathrm{g}) (\mathrm{x}) =21.2 \mathrm{x}+358$ ; this is the total number of lawyers, in thousands, in a œrtain country x years after 1995.
(ii) 1312; there will be 1,312,000 lawyers in a certain country in theyear 2040.
D) (i) $(\mathrm{f}+\mathrm{g}) (\mathrm{x}) =226.1 \mathrm{x}+153.1$ ; this is the total number of lawyers, in thousands, in a certain country x years after 1995 .
(ii) 10,327.6; there will be 10,327,600 lawyers in a certain country in the year 2040.
