To determine how many overtime hours Sam Brown needs to work to meet his monthly pledge of \$50, let's break down the calculations:

1. **Regular Pay Rate:**
   - **Straight Time Rate:** \$7.80 per hour.

2. **Overtime Pay Rate:**
   - **Time and a Half:** $$ 1.5 \times \$7.80 = \$11.70 $$ per hour.

3. **Amount Needed from Overtime:**
   - **Monthly Pledge:** \$50.

4. **Calculating Overtime Hours:**
   - To find the number of overtime hours required to earn \$50:
     $$
     \text{Overtime Hours} = \frac{\text{\$50}}{\text{\$11.70 per hour}} \approx 4.27 \text{ hours}
     $$
   - Since you can't work a fraction of an hour in most cases, you round up to the next higher whole hour.

5. **Final Answer:**
   - **Overtime Hours Needed:** **5 hours**

Sam needs to work **5 overtime hours** each month to meet his \$50 pledge.
