Answer:
75%
Step-by-step explanation:
Use formula:
[tex]\text{Percentage of Change}=\dfrac{\text{New Value}-\text{Old Value}}{\text{Old Value}}\cdot 100\%[/tex]
In your case,
Old Value = $20.00
New value = $35.00
So, the percentage of change is
[tex]\dfrac{35-20}{20}\cdot 100\%=\dfrac{15}{20}\cdot 100\%=15\cdot 5\%=75\%[/tex]
