Let 
be the amount of food needed for one man for one day. At the beginning, we have enough food for 400 men for 40 days, i.e.
After 10 days, the 400 men will have consumed
food, impliying that the food remaining is
If 200 more men join the garrison, there are now 600 men. Each of them requires food each day, and there are

Answer:
7/4 or 1.75 drops
Step-by-step explanation:
In one gallon there are 128 ounces, if it takes 28 drops of coloring to turn 128 ounces of milk green then:
28/128
7/32
it takes 7/32 drops of food coloring to turn one ounce of milk green.
for 8 ounces, you multiply it by 8:
8*7/32
7/4≈1.75
∴ It would take 1.75 or 7/4 drops of coloring to turn 8 ounces of milk green.
A.The given value of 9000 for the volume would increase because when moving in units meters to centimeters it would increase from 9000m to 900,000cm
