The correct option is B 10,000
Number of pages printed in 10 minutes = 100
Number of pages printed in 1 minute = 100 ÷ 10 = 10
Number of pages printed in 1,000 minutes = 10 × 1000
To mulitply a number by 1000, we have to add three zeros to the right of the number.
⟹ 10 × 1000 = 10,000 dollars
Hence, the number of pages printed in 1000 minutes = 10,000
