Answer:
50%
Explanation:
You could make an equation:
200+(x/100*200)=300
x/100*200=100
200x/100=100
200x=10000
x=50
OR you could use this formula:
Percent Change = (Amount of Change/Beginning Amount) *100
Percent Change = (300-200/200)*100
Percent Change=1/2*100
Percent change = 50%
hope this helps!
