Answer:
25%
Step-by-step explanation:
The formula for finding change over time
P= N-O/O times 100
P= percent
N= new value (for this problem 40)
O= old value (for this problem 32)
100 to get the percentage
First, subtract 32 from 40 to get 8.
Then, divide 8 by 32 to get 0.25
Lastly multiply by 100 to get 25 which is your percentage of change
