a
Wage Rate Decrease: When the wage rate for toothbrush workers decreases, it typically indicates a shift in the supply or demand for labor
b
Increase in Employment: The increase in the number of toothbrush workers employed suggests that the demand for labor has increased or the supply of labor has decreased
