From the model,

4 units + 5 units + 7 units ----------> $12800

16 units ----------> $12800 / 16 units = $800

4 units ----------> 4 units x $800 = $3200

5 units ----------> 5 units x $800 = $4000

7 units ----------> 7 units x $800 = $5600

Therefore,

A receives $3200,

B receives $4000,

C receives $5600.
