Final answer:
After calculating the discounted prices, Carly would find the best price for the iPhone at Walmart, which would be $436.00 compared to Best Buy's $450.00.
Step-by-step explanation:
To determine the best price for the iPhone, we need to calculate the discounted prices at both Walmart and Best Buy given the original prices and the respective discounts.
At Walmart, the iPhone is originally priced at $545.00 with a 20% discount. To calculate the discounted price, multiply the original price by the discount percentage and then subtract that amount from the original price:
- $545.00 × 20% = $109.00 discount
- $545.00 - $109.00 = $436.00 after discount
At Best Buy, the iPhone has an original cost of $600.00 with a 25% discount. Let's do a similar calculation:
- $600.00 × 25% = $150.00 discount
- $600.00 - $150.00 = $450.00 after discount
Comparing the two prices, Carly would get the best price at Walmart, where the iPhone costs $436.00 after the discount is applied. This is lower than the Best Buy discounted price of $450.00.
