5

6.

2. Solution Steps

The formula for percentage increase is:

$Percentage\ Increase = \frac{New\ Value - Original\ Value}{Original\ Value} \times 100$

First, we find the difference between the new value and the original value:

$Difference = 156 - 130 = 26$

Then, we divide the difference by the original value:

$Fraction = \frac{26}{130} = \frac{1}{5}$

Finally, we multiply the fraction by 100 to express the result as a percentage:

$Percentage\ Increase = \frac{1}{5} \times 100 = 20$

3. Final Answer

The percentage increase is 20%.
