Answer:
adult; inelastic.
Step-by-step explanation:
Data provided in the question
Increase wage rate percentage is 10%
And, the given supply percentage is 7%
As there is no information given in the question related to the teenager and adult so we assume that the data is given for adult
Since the wage rate is increase by 10% which reflects the adults worker and due to which the supply is 7% more labor. So the elasticity of labor supply is inelastic as the supply is less than the wage rate so it cannot be perfectly elastic
