Q#2. Mudassir Hussain, a PhD scholar at National University of Austria, need to make phone calls within Austria, to the United States, and to Pakistan. The rates per minute for these calls varies for within and| outside the country. Use the information in the following table to determine the call rates. Transform this information in to system of linear equations and solve it using the matrix method or the simultaneous equation method. Let x1 represent the rate for calls within Canada. Let x2 represent the rate for calls to the United States. Let x3 represent the rate for calls to Pakistan.
