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.

  • 40% = 40/100

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
