Do not reproduce without written permission. 1. Begin with the total cost formula: Total cost = fixed costs + (variable costs/unit * volume), or algebraically: TC = a + bx, where a is the fixed cost component and b is variable costs/unit. 2. Apply the formula to June, as follows: $1,500 = a + b (10,000); a = $1,500 – 10,000b 3. Then, apply the formula to July, as follows: $1,700 = a + b (12,000) 4. Substitute from the June equation, as follows: $1,700 = ($1,500 – 10,000b) + 12,000b 5. This permits us to solve for b, as follows: $200 = 2,000b; b = $.10 6. We can then solve for a: a = $1,500 – 10,000 ($.10) = $500 7. Our total cost formula therefore is TC = $500 + $.10 * kilowatt hours 8. We can test this with July: TC = $500 + $.10 (12,000) = $1,700 Scatter Diagram Method. With a scatter diagram method, we have several data points, wh...
