A company used about [tex]7.4 \times 10^5[/tex] sheets of paper in a month. Of the paper used during the month, the accounting department used about [tex]8.9 \times 10^3[/tex] of the sheets.
About how many sheets of paper were used by other departments during the month?
Answer (2)
The company used 7.4 x 10⁵ sheets of paper. That's 740,000 .
The accounting department used 8.9 x 10³ sheets. That's 8,900 .
Everybody else used (740,000 - 8,900) = 731,100 . That's 7.311 x 10⁵ .
That was a lotta trees !
The other departments used approximately 731,100 sheets of paper, which can be expressed as 7.311 × 1 0 5 in scientific notation.
