E!) In this question we are considering inputoutput models. a) Write down the equation giving the production vector X in terms of the extemal demand vector D, and the technology matrix A. [1} [1.5 [1.1 t] b) lGiven the technology matrix A = D [1.5 [L1] and the external demand vector [1.5 D [1.5 24 43%], find the corresponding production vector X. {S} 960 D: Tip: Eliminate fractions early in the solution and only at the end use fractions {not decimals}
