Apple Inc. manufactures iPhones. The total production cost for the month of July amounted to $1,000,000. The company's cost accountant provided the following cost data:

• Variable Costs: $500,000
• Fixed Costs: $300,000
• Mixed Costs: $200,000

Using the high-low method, determine the fixed and variable components of the mixed costs. Then, prepare a cost equation for the mixed costs and predict the total mixed costs if iPhone production levels increase by 20%.
