The Costs of Quality Are Given by the Following Equations

Short Answer

The costs of quality are given by the following equations:
Cₐ = 20D + 5000
Cp = 15000-100D
Cf = 50 × eᴰ/⁴
where:
Cₐ is the cost of appraisal,
Cp is the cost of prevention,and
Cf is the cost of failure.Note that D is the percent defectives and 0 < D < 100.What will be the prevention cost if D = 15 percent?
