The formula to calculate the New Value (NV) is:
\[ NV = BV \times \left( 1 + \frac{RC}{100} \right) \]
Where:
Let's say the base value (BV) is $100 and the relative change (RC) is 20%. Using the formula:
\[ NV = 100 \times \left( 1 + \frac{20}{100} \right) \]
We get:
\[ NV = 100 \times 1.2 = 120 \text{ dollars} \]
So, the new value is $120.
