To find the discounted price of a pair of roller skates that originally costs $65 and is discounted by 40%, we need to follow these steps:
1. Identify the normal price and the discount percentage:
- Normal price \( = \$65 \)
- Discount percentage \( = 40\% \)
2. Convert the discount percentage to a decimal:
- \( 40\% \) can be written as \( \frac{40}{100} = 0.40 \)
3. Calculate the amount of the discount:
- The discount amount is the normal price multiplied by the discount percentage.
- Discount amount \( = 65 \times 0.40 = \$26.00 \)
4. Subtract the discount amount from the normal price to get the discounted price:
- Discounted price \( = 65 - 26 = \$39.00 \)
So, the discounted price of the roller skates is [tex]\( \$39.00 \)[/tex].
