Dylan Products has a budget of$1,200,000 in 2018 for prevention costs. If it decides to automate a portion of its preventionactivities, it will save$90,000 in variable costs. The new method will require$40,000 in training costs and$150,000 in annual equipment costs. Management is willing to adjust the budget for an amount up to the cost of the new equipment. The budgeted production level is210,000 units.

Appraisal costs for the year are budgeted at$500,000. The new prevention procedures will save appraisal costs of$50,000. Internal failure costs an averageof $20 per failed unit of finished goods.

External failure costs average$48 per failed unit. Thecompany's average external failures average2.5% of units sold. The new proposal will reduce this rate to1%. Assume all units produced are sold and there are no ending inventories.
