Answer:
75% increase
Step-by-step explanation:
Percent change can be found using:
difference in values/original value * 100
The difference in the values is 3. Difference means subtraction (7-4=3). The original value is 4, since it changed from four to seven. So, we can substitute 3 in the numerator, and 4 in the denominator.
3/4*100
0.75*100
75
75% change
It is an increase, since we went from four to seven.
So, it is a 75% increase.
