A certain country had a total annual expenditure of $7.2 x 10^11 last year. If the population of the country was 240 million last year, what was the per capita expenditure?
Choose the correct choice from the following answers
A) $ 500	B) $1,000	C) $2,000	D) $3,000	E) $5,000
Total expenditure / Population = per capita expenditure   Hence, (7,2 x 10^11) / 240 000 000 = (7,2 x 10^11) / (2,4 x 10^8) = 3 x 10^(11-8) =   3 x 10^3 = 3000.   Answer is $3,000.
