1. **State the problem:** Floyd earns a base rate of 200 per month plus 12 for each album sold. Last month, he earned a total of 644. We need to find how many albums he sold.
2. **Set up the equation:** Let $x$ be the number of albums sold. The total earnings can be expressed as:
$$200 + 12x = 644$$
3. **Solve for $x$:**
Subtract 200 from both sides:
$$12x = 644 - 200$$
$$12x = 444$$
Divide both sides by 12:
$$x = \frac{444}{12}$$
$$x = 37$$
4. **Interpretation:** Floyd sold 37 albums last month.
**Final answer:** Floyd sold **37** albums last month.
