Tesla Inc. produces three types of cars: Model S, Model 3, and Model X. The following data is available:

• Model S: Direct Materials: $50,000,000; Direct Labor: $25,000,000; Overhead Rate: 170%
• Model 3: Direct Materials: $45,000,000; Direct Labor: $20,000,000; Overhead Rate: 170%
• Model X: Direct Materials: $60,000,000; Direct Labor: $30,000,000; Overhead Rate: 170%

Requirements:

1. Compute the total manufacturing cost for each car model.
2. Determine the total overhead applied to each car model.
3. Prepare a cost sheet for each model.
4. Calculate the break-even point in units if the selling prices are $70,000, $50,000, and $80,000 for Model S, Model 3, and Model X, respectively.
5. Evaluate the cost structure and suggest areas for improvement.
