Answer:
2
Step-by-step explanation:
We know that the opposite sides of a parallelogram are equal so:
25x+1=7x+37
18x=36
x=2
You have to know the difference in change, so you do 59-31 and you get 28, then since you want to know the change in percent you divide the difference, which is 28 and divide that by 31, which is the original amount consumed, and you get 28/31, and you get .90 which is 90%
