Answer 1

To calculate the percent of increase, you can use the formula:

\[ \text{Percent Increase} = \left(\frac{\text{New Value} - \text{Old Value}}{\text{Old Value}}\right) \times 100 \]

In this case, the Old Value is 30 million (the number of people using food stamps in March 2007) and the New Value is 43.7 million (the number of people using food stamps in March 2009).

Now, plug in the values:

\[ \text{Percent Increase} = \left(\frac{43.7 - 30}{30}\right) \times 100 \]

\[ \text{Percent Increase} = \left(\frac{13.7}{30}\right) \times 100 \]

\[ \text{Percent Increase} = 0.4567 \times 100 \]

\[ \text{Percent Increase} \approx 45.67% \]

So, the percent of increase in the number of people using food stamps is approximately 45.67%.
