Final answer:
To make a 35% profit on an iPhone that costs $800, you should sell it for $1080, which includes the original cost plus the profit.
Step-by-step explanation:
To calculate the selling price of the iPhone to make a 35% profit margin, you should first determine the amount of profit you want to make on the $800 iPhone. To do this, multiply the cost of the iPhone ($800) by the desired profit percentage (35%).
Profit = Cost × Profit Percentage
Profit = $800 × 0.35
Profit = $280
Now, add the profit to the original cost to find the selling price:
Selling Price = Cost + Profit
Selling Price = $800 + $280
Selling Price = $1080
Therefore, to achieve a 35% profit, the iPhone should be sold for $1080.
