Solve the problem.The following table shows the market prices per pound that a trucker can get for his load of fruit in three cities: San Francisco (S.F.), Las Vegas (L.V.), and Los Angeles (L.A).
The trucker has a load of 6000 pounds of peaches and 3000 pounds of apples. Write the information from the table as a 2 x 3 matrix B. Write a row matrix A for which the entries represent the number of pounds of each type of fruit in the truck. If 
, find c11. What does this entry of C represent?
A. c11 = 3250. c11 represents the total value of the load in Las Vegas. B. c11 = 4200. c11 represents the total value of the load in San Francisco. C. c11 = 3600. c11 represents the total value of the load in Las Vegas. D. c11 = 6000. c11 represents the total value of the load in San Francisco.
