- A factory manufactures three products (doohickies, gizmos, and widgets) and ships them to two warehouses for storage. The number of units of each product shipped to each warehouse is given by the matrix A=[20015010075100125] (where aij is the number of units of product i sent to warehouse j and the products are taken in alphabetical order). The cost of shipping one unit of each product by truck is $1.50 per doohickey, $1.00 per gizmo, and $2.00 per widget. The corresponding unit costs to ship by train are $1.75, $1.50, and $1.00. Organize these costs into a matrix B and then use matrix multiplication to show how the factory can compare the cost of shipping its products to each of the two warehouses by truck and by train.arrow_forwardDetermine the dimension of the matrix 14710238.arrow_forwardGasoline Sales Matrix A shows the numbers of gallons of 87 octane, 89 octane, and 93 octane gasoline sold at a convenience store over a weekend. 878993OctaneA=[5808403205604201608601020540]FridaySaturdaySunday Matrix B gives the selling prices in dollars per gallon and the profits in dollars per gallon for the three grades of gasoline.
