Solve the problem.The value of certain make and model of used car can depend on several factors. The table gives data for the values of three Chevy Caprice station wagons.The value V is measured in dollars, where A is the age of the car in years, and C is the condition of the car rated on a scale of 1 to 10 ( 10 is excellent condition ) .The variables are found to be related by the equation  Use the information given in the table to write a matrix equation which when solved will yield the values of a, b, and c. Then, using the fact that the inverse of the matrix
