I need to know the formulas so I can but them on excel myself

Problem I: The weekly output of a production process is shown below together with data for labor and material inputs. The standard value of the output is S24 per unit. Assume a 40 hour- week and an hourly wage rate of S18.50. Material cost is $48 per unit. Overhead is charged according to one of the following equations. (a) Equation A: Overhead S1,000 plus 0.88 times the total labor cost; (b) Equation B: Overhead S8,500 plus 0.25 times the total material cost and (c) Equation C: Overhead S2,700 plus 0.46 times the total of labor and material costs. Calculate a. Labor productivity per week, b. Material productivity per week, c. Multi-factor productivity per week using overhead A, d. Multi-factor productivity per week using overhead B, c. Multi-factor productivity per week using overhead C, f. What is your conclusion with respect to labor productivity? g. What is your conclusion with respect to material productivity? h. What is your conclusion with respect to multi-factor productivity (option A)? i. What is your conclusion with respect to multi-factor productivity (option B)? j. What is your conclusion with respect to multi-factor productivity (option C)?
