Final answer:
To earn a profit of $10,000,000, Apple needs to sell 100,000 units of the new iPhone in one month.
Step-by-step explanation:
To find the number of units Apple needs to sell in one month to earn a profit of $10,000,000, we can use the formula:
Number of units sold = (Fixed costs + Desired profit) / (Selling price - Cost of production)
Substituting the given values, we get: Number of units sold = ($10,000,000 + $10,000,000) / ($500 - $300) = $20,000,000 / $200 = 100,000 units.
Therefore, Apple needs to sell 100,000 units in one month to earn a profit of $10,000,000.
