Question 108047
Write all equations that would be used to solve this system.Be sure to define all variables. 
........Jambalaya/ Crawfish pie/ File' gumbo/ Iced tea/ Dessert/ cost 
Boudreax 36.......... 28........... 35.......... 90......68 .......344.35
Thibodeaux 37 19 56 84 75 369.10
Fontenot 49 55 70 150 125 588.90
Arceneaux 58 34 52 122 132 529.50
Gautreaux 44 65 39 133 120 521.65 
Write the matrix A=
write the matrix B=
write the matrix x= 
------------
Let unit price of Jambalaya be "a"; unit price of Crawfish pie be "b",
unit price of File gumbe be "c",......."d",......"e"
-------------------------
EQUATIONS:
36a +28b + 35c + 90d + 68e = 344.45
37a +19b + 56c + 84d + 75e = 369.90
etc.
Matrix A has all the coefficients:
36.......... 28...........35.........90......68 
37...........19...........56.........84......75
etc.
--------------
Matrix B has all the cost numbers:
344.45
369.90
etc
-------------
Matrix "x" has all the answers:
a = 2.85
b = 1.85
c = 1.75
d = 0.75
e = 0.90
