Question

Fifty-five percent of the 4000 customers placed orders, using the company’s online service. How many customers did not order online?

Answer 1

1,800 customers did not order online. 55% did. 50% of 4000 is 2000. 5% of 4000 is 200. 55% is 2200. 4000-2200=1800.

Answer 2

1,800
55% of 4000 is 2200
45% (what is left over, those who did not order online) is 1800
