• A. 4,000 dollars
• B. 400 dollars
• C. 40,000 dollars
• D. 1004 dollars

Answer 1

The correct option is A 4,000 dollars

Price of a chair = 40 dollars

Total cost of 100 such chairs = 40 $\times$ 100

To mulitply a number by 100, we have to add two zeros to the right of the number.

$⟹$ 40 $\times$ 100 = 4000 dollars

Hence, total cost of 100 chairs = 4,000 dollars.
