2. Rosa is the manager of a fine-dining Italian restaurant in a large Midwest city. She has experienced high turnover with her hourly employees over the past several months because they say that she isn't paying competitive wages. More employees have threatened to leave if she doesn't give them a raise. She has determined that she can compete with local restaurants if she raises the hourly wage from [tex]\$8.00[/tex] per hour to [tex]\$8.50[/tex], a 6.25 percent increase. Rosa is concerned about what this will do to her labor cost percentage. Her current labor cost is 35 percent, and she feels that 38 percent is the highest labor cost ratio she can maintain and still make a profit. Using last month's data, help Rosa calculate the effect of a 6.25 percent increase in wages.

To help Rosa calculate the effect of a 6.25 percent increase in wages on the labor cost percentage, we can follow these steps:

### 1. Calculate Raise in Dollars for Each Week
First, determine the increase in labor costs for each week due to the wage increase from [tex]$\$[/tex]8.00[tex]$ to $[/tex]\[tex]$8.50$[/tex] per hour (a 6.25 percent increase).

- Week 1:
[tex]\[ \$10,650 \times 0.0625 = \$665.625 \][/tex]
- Week 2:
[tex]\[ \$12,075 \times 0.0625 = \$754.6875 \][/tex]
- Week 3:
[tex]\[ \$10,887 \times 0.0625 = \$680.4375 \][/tex]
- Week 4:
[tex]\[ \$10,383 \times 0.0625 = \$648.9375 \][/tex]

### 2. Calculate Total Cost of Labor for Each Week After the Raise
Next, add the raise in dollars to the original cost of labor for each week.

- Week 1:
[tex]\[ \$10,650 + \$665.625 = \$11,315.625 \][/tex]
- Week 2:
[tex]\[ \$12,075 + \$754.6875 = \$12,829.6875 \][/tex]
- Week 3:
[tex]\[ \$10,887 + \$680.4375 = \$11,567.4375 \][/tex]
- Week 4:
[tex]\[ \$10,383 + \$648.9375 = \$11,031.9375 \][/tex]

### 3. Calculate the Labor Cost Percentage for Each Week After the Raise
Now, calculate the labor cost percentage for each week after the raise:

- Week 1:
[tex]\[ \left( \frac{\$11,315.625}{\$27,600} \right) \times 100 \approx 40.9986\% \][/tex]
- Week 2:
[tex]\[ \left( \frac{\$12,829.6875}{\$32,250} \right) \times 100 \approx 39.7820\% \][/tex]
- Week 3:
[tex]\[ \left( \frac{\$11,567.4375}{\$28,650} \right) \times 100 \approx 40.3750\% \][/tex]
- Week 4:
[tex]\[ \left( \frac{\$11,031.9375}{\$37,200} \right) \times 100 \approx 29.6557\% \][/tex]

### 4. Calculate Totals and Average Labor Cost Percentage
Finally, compute the totals and average labor cost percentage.

- Total Original Cost of Labor:
[tex]\[ \$10,650 + \$12,075 + \$10,887 + \$10,383 = \$43,995 \][/tex]
- Total Raise in Dollars:
[tex]\[ \$665.625 + \$754.6875 + \$680.4375 + \$648.9375 = \$2,749.6875 \][/tex]
- Total Cost of Labor After Raise:
[tex]\[ \$11,315.625 + \$12,829.6875 + \$11,567.4375 + \$11,031.9375 = \$46,744.6875 \][/tex]
- Total Sales:
[tex]\[ \$27,600 + \$32,250 + \$28,650 + \$37,200 = \$125,700 \][/tex]
- Average Labor Cost Percentage:
[tex]\[ \left( \frac{\$46,744.6875}{\$125,700} \right) \times 100 = 37.1875\% \][/tex]

### Tabulated Results:
[tex]\[ \begin{array}{|l|r|r|r|r|r|} \hline \text{Week} & \text{Original Cost of Labor} & \text{Raise in Dollars} & \text{Total Cost of Labor} & \text{Sales} & \text{Labor Cost \%} \\ \hline 1 & \$10,650 & \$665.625 & \$11,315.625 & \$27,600 & 40.9986\% \\ \hline 2 & \$12,075 & \$754.6875 & \$12,829.6875 & \$32,250 & 39.7820\% \\ \hline 3 & \$10,887 & \$680.4375 & \$11,567.4375 & \$28,650 & 40.3750\% \\ \hline 4 & \$10,383 & \$648.9375 & \$11,031.9375 & \$37,200 & 29.6557\% \\ \hline \text{Total} & \$43,995 & \$2,749.6875 & \$46,744.6875 & \$125,700 & \text{37.1875\%} \\ \hline \end{array} \][/tex]

From the calculations above, raising the hourly wage results in an increase in labor costs percentage to an average of 37.1875%, which is within Rosa's acceptable limit of 38%.
