Answer:Philo should sell.
Step-by-step explanation:
If price falls $2, the final price would be $8. So Philo's income will be:
40 acre x 100 bushel x $8 = $32.000
And costs will be:
Planting cost = $20.000
Harvesting cost = $10.000
Total cost = $30.000
$32.000 - $30.000 = $2.000
So Philo's earning will be $2.000
