Bond Brothers, a real estate developer, builds houses in three states. The projected number of units of each model to be buit in each state is given by the matrix. \[ A=C \text { CT }\left[\begin{array}{rrrr} \multicolumn{5}{c}{\text { Model }} \\ \text { I } & \text { II } & \text { III } & \text { IV } \\ 20 & 80 & 120 & 40 \\ 20 & 30 & 60 & 10 \\ 10 & 15 & 30 & 5 \end{array} ight] \] The profits to be realized are $60,000,$65,000,$73,000, and $85,000, respectively, for each Model I, II, III, and IV house sold. (a) Write a column matrix B representing the profit for each type of house. B=[
