To calculate the Total Paid for each present when \( d = 50 \), we need to follow these steps:
- Calculate the cost after applying the discount.
- Add the additional $2 to the discounted price for the Total Paid.
Let's calculate each present step by step:
1. Power Tools
- Cost: \( d = 50 \)
- Discount: 15%
- Discount amount: \( 15% \text{ of } 50 = 0.15 \times 50 = 7.5 \)
- Price after discount: \( 50 - 7.5 = 42.5 \)
- Total Paid: \( 42.5 + 2 = 44.5 \)
2. Water Skis
- Cost: \( d + 15 = 50 + 15 = 65 \)
- Discount: 25%
- Discount amount: \( 25% \text{ of } 65 = 0.25 \times 65 = 16.25 \)
- Price after discount: \( 65 - 16.25 = 48.75 \)
- Total Paid: \( 48.75 + 2 = 50.75 \)
3. Jewelry
- Cost: \( d - 5 = 50 - 5 = 45 \)
- Discount: 10%
- Discount amount: \( 10% \text{ of } 45 = 0.10 \times 45 = 4.5 \)
- Price after discount: \( 45 - 4.5 = 40.5 \)
- Total Paid: \( 40.5 + 2 = 42.5 \)
Summary of Total Paid for Each Present
- Power Tools: $44.50
- Water Skis: $50.75
- Jewelry: $42.50
Conclusion
The Total Paid for Jewelry is the cheapest option at $42.50. You can circle or star it to indicate that it is the most economical choice.
