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
Answer: A

Scientists have discovered that a linear relationship exists between the amount of flobberworm mucus secretions and the air temperature. When the temperature is 65°F, the flobberworms each secrete 16 grams of mucus a day; when the temperature is 95°F, they each secrete 22 grams of mucus a day. Find a function M(t) that gives the amount of mucus secreted on a given day, where t is the temperature of that day in degrees Fahrenheit.
a. M(t) = 0.2t + 16 b. M(t) = 5t + 16 c. M(t) = 5t + 3 d. M(t) = 0.2t + 3
