3 2 -3 0 -3 3 If A= -3 1 -1 , B= - 3 5 - 4 , and AB = C= [Cjj], find G23- 0 4 4 5 1 - 2 Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. C23= (Simplify your answer.) O B. C23 is not defined because the product AB = C is not defined.A manufacturer produces three products, A, B, and C. The profits for each unit of A, B, and C sold are $1, $2, and $3, respectively. Fixed costs are $18,000 per year, and the costs of producing each unit of A, B, and C are $4, $5, and $7, respectively. Next year, a total of 12,000 units of all three products is to be produced and sold, and a total profit of $23,000 is to be realized. If total cost is to be $80,000, how many units of each of the products should be produced next year? units of product A, units of product B, and units of product C should be produced
