I need help with this question.

Suppose aggregate labour supply is measured as aggregate number of hours worked (L) given wage (w). A. Graph the labour supply if L = 3w. Write the formula for the (total) elasticity of labour supply in this case and substitute out L. After simplifying, the (total) elasticity of labour supply is B. Graph the labour supply if L = 14w. Write the formula for the (total) elasticity of labour supply in this case and substitute out L. After simplifying, the (total) elasticity of labour supply is C. Graph the labour supply if L = 3w - 1. Write the formula for the (total) elasticity of labour supply in this case and substitute out L
