Final answer:
Store 1 offers the best price after a 10% discount, bringing the cost down to $24.30 with a 5-year warranty. Store 2 has no discount and a 3-year warranty, and Store 3 has a higher price of $30 but a 4-year warranty.
Step-by-step explanation:
To determine which store offers the best price, we must consider both the price after the discount and the value of the warranty provided. Let's calculate the discounted price for Store 1:
- Original Price: $27
- Discount: 10% of $27 = $2.70
- Discounted Price: $27 - $2.70 = $24.30
Store 2 has the same original price of $27 but no discount and a shorter warranty. Store 3 has a higher price of $30 and a longer warranty than Store 1 but shorter than Store 2.
Based on the discounted price and warranty length, Store 1 offers the best deal with a price of $24.30 and a 5-year warranty. However, if warranty length is more important to the customer than the initial discount, they might prefer Store 3 despite its higher price. It's essential to weigh both the price and the warranty length based on personal preference and the value of the warranty offered.
