Quality versus costs. Vince Mansuetti has discovered a problem involving the mix of lye to the dry concrete mix that costs the company $10,000 in waste and $7,000 in lost business per period. There are two alternative solutions. The first is to lease a new mix regulator at a cost of $7,000 per period. The new regulator would save Vince $7,000 in waste and $4,000 in lost business. The second alternative is to hire an additional employee to manually monitor the existing regulator at a cost of $6,000 per period. This would save Vince $5,000 in waste and $4,000 in lost business per period.

Which alternative should Vince choose?
