The estimated population of Luxembourg is 640,000, while Brazil is estimated at 214 million. Using these estimates and the Figure above, calculate the total
CO2 emissions in tonnes for both countries.
A. 1,779,200 ;579,940,000
B. 1,734,400; 594,920,000
C. 2.78; 2.71
D. 278,000,000; 271,000,000
参考答案: A
本题详细解析:
Multiply the population estimate by the g/ k4s4xkg;rj i)* onmamount per capita (which means the amount krn4soj 4xi/)g;m*k g per person).
Luxembourg =640,000×2.78640,000×2.78= 1,779,200 tonnes
Brazil =214,000,000×2.71214,000,000×2.71= 57,994,000 tonnes
