Let's assume in 2006 he has sold X. Therefore in 2007 he should have sold 97/100×X.

97/100×2100=2037
-->2,037,000 sold in 2007. When rounded to the nearest 10,000 :

2,040,000

Let's assume in 2006 the manufacturer sold X.
In 2007 he sold X-3/100(X)

If sales in 2006,X= 2.1 million find X-3/100(X)

(2.1 x 10^6)-3/100(2.1 x 10^6)

2100000-63000=2,037,000-----> 2,040,000(approx)

D :-D
is my answer after rounding

3% of 2,100,000 is 63,000
2,100,000-63,000=2,037,000
nearest 10,000 is choice D
