Explanation / Answer
Matrix A
Burgers fries soft drinks
Location 1 900 600 750
Location 2 1500 950 900
Location 3 1150 800 825
Matrix B
Price
Burger 1.50
Fries 0.90
Soft drink 0.60
A * B = 900 600 750 1.50
1500 950 900 * 0.90
1150 800 825 0.60
=> ( 900 * 1.50 + 600 * 0.90 + 750*0.60 ) = 2340
=> (1500 * 1.50 + 950 * .90 + 900 * .60 )= 3645
=> (1150 * 1.50 + 800 * .90 + 825 * .60 )=294
= 2340 + 3645 + 2940
= 8925
