Hi there! To find the percent of change, do change/original = x/100. The amount of change means to find the distance between two numbers and the original is the previous price. 108 - 90 = 18. Plug in the values in order to get 18/90 = x/100. Cross multiply the values in order to get 1,800 = 90x. Now, divide each side by 90 to isolate the variable. When you do, you get x = 20. The store increased their prices by 20%.

The word problem gives you the information you need to solve it.
5 batches of chili were made using 63.5 kg of beans total. You can assume the same amount of beans were used in each of the 5 batches, so ...
your equation would be:
63.5 ÷ 5 = # of beans in each batch.
63.5 ÷ 5 = 12.7
12.7 kg of beans were used in each of the 5 batches.
Check step:
12.7 × 5 = 63.5
