Answer:
$5.08 per shirt
Step-by-step explanation:
5 Indonesian laborers work 60 hours per week = 300 hours per week
they are paid $3.50 per day x 6 days x 5 workers = $105 per week
they produce 500 shirts per week, so the labor cost per shirt = $105 / 500 = $0.21 per shirt
if the firm operated in the US, they would need to pay each worker:
(40 x $7.25) + (20 x $10.88) = $507.60 per worker x 5 workers = $2,538
if they produce 500 shirts, the labor cost per shirt = $2,538 / 500 = $5.08 per shirt
