Answer:
$7.1345 per shirt
Step-by-step explanation:
depreciation expense per year = $17,500 / 3 = $5,833
initial outlay = -$17,500
cash flow year 1 = [(5,000X - $20,000 - $8,000 - $5,833.33) x 0.79] + $5,833.33 = 3,950X - $20,895
cash flow year 2 = [(5,000X - $20,000 - $8,000 - $5,833.33) x 0.79] + $5,833.33 = 3,950X - $20,895
cash flow year 3 = [(5,000X - $20,000 - $8,000 - $5,833.33) x 0.79] + $5,833.33 = 3,950X - $20,895
$17,500 = (3,950X - $20,895)/1.12 + (3,950X - $20,895)/1.12² + (3,950X - $20,895)/1.12³
$17,500 = 3,526.79X - $18,656.25 + 3,148.92X - $16,657.37 + 2,811.53X - $14,872.65
$17,500 = 9,487.24X - $50,186.27
$67,686.27 = 9,487.24X
X = $67,686.27 / 9,487.24 = $7.1345 per shirt
