Answer:
The level of pretax cost savings we require for this project to be profitable is $203272.65
Explanation:
investment in fixed assets + investment in NWC = pretax cost savings*(1-t)*PVIFA(R%,n) + PV of dep tax shield + PV of salvage + PC of NWC
let a be the pretax cosy savings, then:
835000 + 95000 = a*(1-0.25)*3.69589702 + 170786.28 + 64537.83 + 56377.88
930000 = 2.771922765*a + 291701.99
2.771922765*a = 638298.01
a = $230272.65
Therefore, The level of pretax cost savings we require for this project to be profitable is $203272.65.
