Solution:
We know that:
- Discounted price: Original price - (Original price × Discount)
- Original cost of dress: $80
- Discount: 40%
This means that:
- Discounted price of dress: 80 - (80 × 40%)
Step-1: Convert "40%" into a fraction.
Step-2: Find the discounted price.
- Discounted price of dress: 80 - (80 × 40/100)
- Discounted price of dress: 80 - (4 × 40/5)
- Discounted price of dress: 80 - (4 × 8)
- Discounted price of dress: 80 - 32
- Discounted price of dress: $48
