Dusty is evaluating three bids to supply fence hardware for his pasture that need to be fenced. Lady submits a bid of $30 per unit with a defect rate of 5%; Breezy's bid is $40 per unit with a defect rate of 1%; and Spike's bid is $15 per unit with a defect rate of 8%. If a section of fence fails, it costs an average of $500 in losses and herding costs to round up all of the escaped cows. Dusty believes it will take 500 units to fence in this pasture configuration; which supplier should win the business
