1) Since it was 0 years when the college opened, we put x=0 and we get
T=12000
2) 0.03%
3) From 1990 to 2020, it is 30 years. Thus, x=30.
T=12000*(1.03)^30

For future whenever you solve these type, just know that x is a variable and tree have to insert out own value for x according to the questions’s demand.
Answer:
The amount of Soyabean = 608.82 pounds.
The amount of Oats = 900-608.82 = 291.18 pounds.
Step-by-step explanation:
Given that the Soybean Meal has 46% CP and Oats has 12% CP.
The total amount of ration is 900 lbs of 35% CP.
Let x pounds of Soyabean has been used, so,
the amount of Oats = 900-x lbs.
The CP amount in 900 lbs mixture will be equal to the sum of CP amounts in x lbs Soyabean and 900-x lbs Oats, i.e
35% of 900 = 46% of x + 12% of (900-x)
lbs.
So, the amount of Soyabean = 608.82 pounds.
The amount of Oats = 900-608.82 = 291.18 pounds.
