Answer 1

Given:

Emma has 100 notebooks.

She used 20 % of them that means,

$\begin{gathered} 20\text{ percent of 100} \\ \frac{20}{100}\times100=20\text{ notebooks} \end{gathered}$

Remaining books are,

$100-20=80\text{ notebooks}$

Jean had 10% more than that of Emma's remaining notebooks .

10 % of 80 is,

$\frac{10}{100}\times80=8\text{ notebooks}$

The number of jean have is,

$80+8=88\text{ notebooks}$

Answer:

Jean have 88 notebooks
