Step 1 :\( \text{Total visitors} = 9 + 95 + 8 = 112 \)
Step 2 :\( \text{Visitors who purchased exactly 1 costume} = \frac{95}{112} \)
Step 3 :\( \text{Expected visitors next week} = 2000 \)
Step 4 :\( \text{Visitors buying exactly 1 costume} = 2000 \times \frac{95}{112} \approx 1694.64 \)
Step 5 :\( \text{Round to nearest whole number} = 1695 \)
