To calculate the percent change in grocery expenditures from March to April, follow these steps:

1. Identify the grocery expenditures for each month:
- March: \$110.00
- April: \$125.00

2. Calculate the difference in expenditures:
[tex]\[ \text{Difference} = \text{April} - \text{March} = 125.00 - 110.00 = 15.00 \][/tex]

3. Determine the percent change:
The percent change is calculated by dividing the difference by the original amount (March's expenditure) and then multiplying by 100 to get a percentage.
[tex]\[ \text{Percent Change} = \left(\frac{\text{Difference}}{\text{March}}\right) \times 100 \][/tex]
Plugging in the values:
[tex]\[ \text{Percent Change} = \left(\frac{15.00}{110.00}\right) \times 100 \][/tex]

4. Compute the result:
[tex]\[ \text{Percent Change} = 0.13636363636363635 \times 100 \approx 13.64\% \][/tex]

Therefore, the percent change in grocery expenditures from March to April is approximately 13.64%.
