1. Consider the row vector of prices given by [P1, p2 ] = [1, 2] and the column vector of quantities of two goods For income I the budget line can be written as [PI, p2 ] EC1 = I. Verify this by applying the definition of matrix multiplication. 2. We can now write the budget set for any finite number of goods using the technique of matrix multiplication. Consider the row vector of prices given by [P1, P2, P3; P4 ] and the column vector of quantities of two goods C2 Write down the budget line for income
