To solve for , you need to isolate on one side of the equals sign. Add on both sides.
P = 2w + 2l....subtract 2l from both sides
P - 2l = 2w....divide both sides by 2
(P - 2l)/2 = w
Answer:
1320
Step-by-step explanation:
Write a proportion.
22 / 600 = x / 36,000
Cross multiply.
600x = 22 × 36,000
Solve for x.
x = 1320
% of decrease would be 100 - (22*100)/28
=100-78.57 = 21.43%
