To find out how many napkins Isabella bought in total, we can multiply the number of packages by the number of napkins in each package.
Isabella bought 9 packages of paper napkins, and there are 92 napkins in each package.
\[ \text{Total napkins} = \text{Number of packages} \times \text{Number of napkins per package} \]
Substituting the values:
\[ \text{Total napkins} = 9 \times 92 \]
Now we can perform the multiplication:
\[ 9 \times 92 = 828 \]
Thus, Isabella bought a total of 828 napkins.
