Question

B. Lauren bought a new package of notebook

paper containing 300 sheets. She used
27 sheets in a science notebook. What
percent of the paper did she have left?
272

Answer 1

• 91%

Explanation:

• 300 × x/100 = 27
• => 3 × x = 27
• => x = 27/3
• => x = 9

This means that 9% of the notebook is used in science.

• 100% - 9% = Percentage of paper left in notebook.
• => 91% = Percentage of paper left in notebook.

This means that 91% of the notebook pages is remaining.
