From the graph:
The percent increase is calculated using the formula:
Percent Increase = \[ \frac{{\text{New Value} - \text{Old Value}}}{{\text{Old Value}}} \times 100 \]
Percent Increase = \[ \frac{{100,000 - 50,000}}{{50,000}} \times 100 = \frac{{50,000}}{{50,000}} \times 100 = 100\% \]
The percent increase in Store Y’s profits over the course of the 4 months is 100%. Therefore, the correct answer is:
100%
