I think its A. There is a peak in the orders from 6 to 10 pounds
Selling price of 1st buffalo +Selling price of 2nd buffalo=20000
profit for 1st buffalo=0.05 of cost price of 1st buffalo
loss for 2nd buffalo=0.1 of cost price of 2nd buffalo
1.05(cost price of 1st buffalo)+(0.9)cost price of 2nd buffalo=20000
the buffalo must cost must be same = x (say)
1.05x+0.9x=20000
1.95x=20000
x=10256.41
2x=20512.82
profit=20512.82-20000=512.82
profit %=2.56410 %
Answer:
Solving the given linear system, we get x = 1 and y = -3.
The solution set is: (1,-3)
Step-by-step explanation:
We need to solve the linear system of equations.
We can write second equation y=x-4 as: 
Let:
Now, Adding equation 1 and 2
So, we get x = 1
Now, put value of x in second equation to find value of y:
So, we get y = -3
Solving the given linear system, we get x = 1 and y = -3.
The solution set is: (1,-3)
Answer:
I just do a' as a sample. You calculate b' and c'
Step-by-step explanation:
Now, calculate b x c

Multiplying-
Negative times negative is positive
negative times positive is negative
positive times positive is positive
Dividing-
positive divided by positive is positive
negative divided by positive is negative
positive divided by negative is negative
negative divided by negative is positive
Hope this helps!!
