Explanation:

Step1: Find the increase in value

The formula for percent increase is \(\frac{\text{New Value}-\text{Old Value}}{\text{Old Value}}\times100\%\).
The value at the end of week 1 (old value) is \(25\), and the value at the end of week 4 (new value) is \(60\).
The increase is \(60 - 25=35\).

Step2: Calculate the percent increase

Substitute into the formula: \(\frac{60 - 25}{25}\times100\%=\frac{35}{25}\times100\%\).
\(\frac{35}{25}=1.4\), and \(1.4\times100\% = 140\%\).

Answer:

\(140\%\)
