Can anyone help me answer question d?

White Tiger Electronics produces CD players using an automated assembly line process. The standard cost of CD players is $150 per unit (labor, $30; materials, $70; and overhead, $50). The sales price is $300 per unit. Use the formulas below to help solve and also answer question d. A. To achieve a 10 percent multifactor productivity improvement by reducing materials costs only, by what percentage must these costs be reduced? b. To achieve a 10 percent multifactor productivity improvement by reducing labor costs only, by what percentage must these costs be reduced? c. To achieve a 10 percent multifactor productivity improvement by reducing overhead costs only, by what percentage must these costs be reduced? a. A $70 reduction in material costs is $13.64 / $70 = 19.48% b. A $30 reduction in labor costs is $13.64 / $30 = 45.46% C. A $50 reduction in overhead is $13.64 / $50 = 27.28% d. Discuss the feasibility of reducing each of these individual costs in order to achieve the 10 percent multifactor productivity improvement
