Hence, the costs per contact in Rs for different types of contacting the people can be expressed in matrix form as -
Let matrix B contain the number of attempts of each type made in the three villages X, Y and Z.
the total cost incurred by the organization in the three villages for creating awareness can be obtained by taking the product of the matrices B and A.
Cost incurred in village X = Rs 30000
Cost incurred in village Y = Rs 23000
Cost incurred in village Z = Rs 39000
Thus, the cost incurred by the organization in villages X, Y and Z is Rs 30000, Rs 23000 and Rs 39000 respectively.
