To find the amount of increase between an original amount and a new amount, what is the first step?
ASubtract the original amount from the new amount
BSubtract the new amount from the original amount
CDivide the new amount by the original amount
DAdd the new amount and the original amount
Answer & Solution
Correct answer: A. Subtract the original amount from the new amount
1. The formula for finding percent increase starts with finding the plain amount of increase.
2. That amount is defined as the new amount minus the original amount.
3. Only after that difference is found does the next step convert it into a percent of the original amount.
