To find out how many masks Mayerlin keeps in the display case, we first calculate 24% of her total mask collection, which is 400 masks.
\[
\text{Number of masks in display case} = 0.24 \times 400
\]
Calculating this:
\[
0.24 \times 400 = 96
\]
This means Mayerlin keeps 96 masks in the display case. Now, to find out how many masks she keeps on her wall, we subtract the number of masks in the display case from the total number of masks:
\[
\text{Number of masks on the wall} = 400 - 96
\]
Calculating this:
\[
400 - 96 = 304
\]
Thus, Mayerlin keeps **304 masks on her wall**.
\[
\text{Number of masks in display case} = 0.24 \times 400
\]
Calculating this:
\[
0.24 \times 400 = 96
\]
This means Mayerlin keeps 96 masks in the display case. Now, to find out how many masks she keeps on her wall, we subtract the number of masks in the display case from the total number of masks:
\[
\text{Number of masks on the wall} = 400 - 96
\]
Calculating this:
\[
400 - 96 = 304
\]
Thus, Mayerlin keeps **304 masks on her wall**.
