Lawnwolf, a manufacturer of lawn mowers, predicts that it will purchase 324,000 spark plugs next year. Lawnwolf estimates that 27,000 spark plugs will be required each month. A supplier quotes a price of $7 per spark plug. The supplier also offers a special discount option: If all 324,000 spark plugs are purchased at the start of the year, a discount of 4% off the $7 price will be given. Lawnwolf can invest its cash at 8% per year. It costs Lawnwolf $130 to place each purchase order. Required 1. What is the opportunity cost of interest forgone from purchasing all 324,000 units at the start of the year instead of in 12 monthly purchases of 27,000 units per order? 2. Would this opportunity cost be recorded in the accounting system? Why? 3. Should Lawnwolf purchase 324,000 units at the start of the year or 27,000 units each month? Show your calculations. Requirement 1. What is the opportunity cost of interest forgone from purchasing all 324,000 units at the start of the year instead of in 12 monthly purchases of 27,000 units per order? Let's begin the calculation for the opportunity cost of interest forgone by first determining the formula. Then, calculate the opportunity cost. Opportunity cost
