Solve the problem.The value of a 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. Using the fact that the inverse of the matrix
