Sagot :

To calculate the percent change in the restaurant bill from March to April, follow these steps:

1. Determine the restaurant bill amount for both months:
- March: \[tex]$86.00 - April: \$[/tex]86.00

2. Calculate the difference in the restaurant bill between April and March:
[tex]\[ \text{Difference} = \text{Restaurant April} - \text{Restaurant March} \][/tex]
Plugging in the values:
[tex]\[ \text{Difference} = 86.00 - 86.00 = 0.00 \][/tex]

3. Calculate the percent change:
[tex]\[ \text{Percent Change} = \left(\frac{\text{Difference}}{\text{Restaurant March}}\right) \times 100 \][/tex]
Plugging in the calculated difference:
[tex]\[ \text{Percent Change} = \left(\frac{0.00}{86.00}\right) \times 100 = 0.00\% \][/tex]

4. Round to the nearest whole percent:
Since the calculated percent change is [tex]\(0.00\%\)[/tex], there is no need for further rounding.
