Final answer:
After subtracting the amount of corn seed used for planting, the remaining 237.5 pounds are divided among 19 cows, resulting in 12.5 pounds of corn seed for each cow.
Step-by-step explanation:
To determine how much corn seed each of the 19 cows will get, we need to subtract the amount of seed that will be sown from the total, and then divide the remainder by 19. Starting with 400 pounds of corn seed, if 162.5 pounds are used for planting, then 400 - 162.5 = 237.5 pounds are left for feeding the cows. Dividing this amount equally among the 19 cows gives each cow 237.5 / 19 = 12.5 pounds of corn seed.
So, each cow will get 12.5 pounds of corn seed.
