The Vine Lid. sells pre-pack organic vegan meal. The analysis of market data for its vegan meal generates the following demand function D = 100-2P + 0.75/ + 5PR+5A Where D is the quantity demanded for Vine's vegan meal per month, P is the price (in dollars) of each pre-packed meal, Pp is the price of related product (in dollars), / is the per capita disposable income (in thousands of dollars) of the buyers of pre-packed meal and A is the Vine's advertising expenditures. Suppose income (1), advertising expenditure (A), and price of related product (PR ) are given as income (1) = $100, Pp=$5, and A=0 Using the values, derive demand equation (D on the left side) showing D on the left-hand side and P on the right-hand side
