You’ve just made a mistake. We’re quietly judging you.
There were 160 smarties in the box yesterday, but now there are 116, what is the percentage change?
The right answer is: 27.5%
Answer (Method 1): 160 to 116 is a decrease of 44. Compared to yesterday's value: 44/160 = 0.275 = 27.5% decrease. Answer (Method 2): Compare today's value with yesterday's value: 116/160 = 0.725 = 72.5%, so the new value is 72.5% of the old value.
Subtract 100% and you get -27.5%, or a 27.5% decrease.
