A simple calculation using data in the map and in the graph can be performed to find the total number of individuals per $100,000$ who suffered from both HIV and TB in a given country.

For example, in Mexico in $2005,$ the highest number of people who were infected with both HIV and TB is calculated by $(1)$ using the highest percentage $(4\%,$ or $0\mathrm{.}04)$ and $(2)$ multiplying this value with the total number of new TB cases, which is around $65$:

$0\mathrm{.}04\backslash$times $65100,000$

$=0\mathrm{.}000026,$ or $2\mathrm{.}6($rounded to $3)$ people per $100,000$ individuals infected with both TB and HIV.

Assume that in India there were approximately $400$ new TB cases for every $100,000$ individuals in $2005.$ For this same group of $100,000$ individuals, approximate the highest number of individuals who suffered from both HIV and TB in $2005.$ Use the map to help determine the appropriate rates of coincident infection.

$70$ to $80$ individuals

$5$ to $10$ individuals

$100$ to $300$ individuals
