Please explain step-by-step. I am slow and steady learned ;_;

Researchers found the demand for cheese in Mexico for a particular year can be estimated by the implicit equation:

ln q = D -0.44 ln p,

Where p represents the price of a unit of cheese and D represents a constant that can be calculated uniquely for a particular year. Here q represents the annual per capita cheese demand.

(A) Use implicit differentiation to calculate and interpret the elasticity of demand. (Recall from previous section that elasticity of demand is E = -(p/q) * dq/dp.)

(B)Solve the equation for q, then calculate the elasticity of demand.
