2. Three different types of computers need varying amounts of four different types of integrated circuits. The following matrix A gives the number of each circuits needed by each computer. Circuits 1 2 3 4 3 2 1 A = Computers 1 3 3 Let d = (10, 20, 30) be the computer demand vector (how many of each type of computer is needed). Let p = ( $2, $5, $1, $10) be the price vector for the circuits (the cost of each type of circuit). Write an expression in terms of A, d, p for the total cost of the circuits needed to produce the set of computers in demand. Indicate whether the matrix-vector product occurs and where the vector product occurs. Compute this total cost. ABC
