I need help with part A, B, and E. Unsure what i'm doing wrong would appreciate the help.

(c) If Cabinetmaker 1 has additional hours available, would the optimal solution change? Explain. Yes, each additional hour of time for cabinetmaker 1 will reduce the total cost by $1.75 per hour. Yes, each additional hour of time for cabinetmaker 1 will reduce the total cost by $5 per hour. No, cabinetmaker 1 has a slack of 37.5 hours, so increasing cabinetmaker 1 's time will not reduce costs. No, cabinetmaker 1 has a slack of 26.458 hours, so increasing cabinetmaker 1 's time will not reduce costs. (d) If Cabinetmaker 2 has additional hours available, would the optimal solution change? Explain. Yes, each additional hour of time for cabinetmaker 2 will reduce the total cost by $1.75 per hour. Yes, each additional hour of time for cabinetmaker 2 will reduce the total cost by $5 per hour. No, cabinetmaker 2 has a slack of 37.5 hours, so increasing cabinetmaker 2 's time will not reduce costs. No, cabinetmaker 2 has a slack of 26.458 hours, so increasing cabinetmaker 2 's time will not reduce costs. (e) Suppose Cabinetmaker 2 reduced its cost to $38 per hour. What effect would this change have on the optimal solution? Explain. The new objective function coefficients for O2 and C2 are and , respectively. The optimal solution does not change and has a value of $
