Select the correct answer from each drop-down menu. A music recording company has contracts with two bands. It released a new CD from each band in three countries: Britain, Canada, and Australia. The company sold a total of 40,000 CDs in Britain, 50,000 in Canada, and 30,000 in Australia. The advertising cost was $2 per CD in Britain, $1.50 in Canada, and $1 in Australia. If matrix A = [2 1.5 1] and AB represents the total advertising cost (in dollars) for all three countries, the order of matrix B is 3 x 1 , and the order of matrix AB is 1 x 1 . The total advertising cost for all three countries is $ 120,000
