Final answer:
The percent increase in the price of AirPods is calculated by dividing the difference between the selling price and the cost price by the cost price, and then multiplying by 100.
The difference is $40, and the percent increase is found to be 50%.
Step-by-step explanation:
The question asks to calculate the percent increase in the price of AirPods when they are sold by Best Buy compared to the purchase price from manufacturers.
We start by finding the difference between the selling price and the cost price.
The selling price of the AirPods is $120, and the cost price is $80.
The difference between these two prices is $120 - $80 = $40.
Next, we need to find what percentage $40 is of the original price ($80).
To find the percent increase, we divide the increase ($40) by the original price ($80) and multiply by 100.
So, the percent increase is calculated as follows:
- Percent Increase = ($40 / $80) * 100
- Percent Increase = 0.5 * 100
- Percent Increase = 50%
Therefore, the percent increase in price from the manufacturer's cost to the selling price at Best Buy is 50%.
