Answer:
Operating revenue, R = $300000
Operating Cost, C = $280000
Fixed Cost, F = $40000
Salvage value of fixtures, S = $15000
If it remains open, its value will be = R - C - F + S = 300000 - 280000 - 40000 + 15000 = -$5,000
If the salon closes down, its value will be = S - F = 15000 - 40000 = -$25000 .
Fran should remain open as the value of the salon if remaining open (-$5,000) is more than the value of closing it (-$25,000).
