Final answer:
The better option is to purchase the laptop at Best Buy for $985.95 with a 10% off coupon, making the final price $887.36 after discount, which is cheaper than Walmart's price of $915.50 by $28.14.
Step-by-step explanation:
To determine the better option for buying a laptop between Walmart and Best Buy, we need to calculate the price at Best Buy after applying the 10% off coupon. The original price at Best Buy is $985.95. A 10% discount on $985.95 can be calculated as 0.10 Ă— $985.95 = $98.595. When you subtract this discount from the original price, you get $985.95 - $98.595 = $887.355. However, when dealing with currency, we round to the nearest cent, so the discounted price at Best Buy would be $887.36.
Comparing the two prices:
- Walmart: $915.50
- Best Buy (with discount): $887.36
It is clear that the laptop at Best Buy with the 10% off coupon is the cheaper option by $28.14.
