A. 154 in. B. 139 in. C. 298 in. D. 149 in.
Based on its existing sales, what is the formula for calculating the full-capacity sales of a firm?
A. Full-capacity sales = Existing sales level ÷ Percent of capacity used to generate existing sales level B. Full-capacity sales = Future sales level ÷ (1 - Percent of capacity used to generate existing sales level) C. Full-capacity sales = Future sales level ÷ Percent of capacity used to generate existing sales level D. Full-capacity sales = Future sales level ÷ (1 + Percent of capacity used to generate existing level of assets) E. Full-capacity sales = Existing sales level ÷ (1 - Percent of capacity used to generate existing level of assets)

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. Then, using the fact that the inverse of the
matrix 
is 
, find c.
A. c = 400
B. c = 200
C. c = -200
D. c = -400
