1. The problem asks for the total cost of buying one iPhone and one Android phone. 2. To solve this, we need the individual prices of the iPhone and the Android phone. 3. Since the prices are not provided in the question, we cannot calculate the total cost. 4. If prices were given, the formula would be: $$\text{Total Cost} = \text{Price of iPhone} + \text{Price of Android}$$ 5. Without the prices, the answer is indeterminate from the given information.
