Answer:
2750
Explanation:
Remark
You have to assume that this can be solved by using a proportion. A proportion is 2 equal ratios. Three parts of the 2 ratios must be known and your job is to find the 4th one.
Equation
w*L/C1 = w1*L1 / x
Solution
w = 8
L = 10
w1 = 20
L1 = 25
C1 = 449
C2= x
Solution
8*10/440 = 20*25/x Combine
80/440 = 500 / x Cross Multiply
80x = 440*500 Combine
80x = 220000 Divide by 80
x = 220000/80
Answer
x = 2750
