S is 3x5
T is 5x2
So, you get a 3x2 matrix, one row for each outlet, one column for wholesale/retail.
So, what do you think?
A company sells five models of computers through three retail outlets. The inventories are represented by S. The wholesale and retail prices are represented by T. Compute ST and interpret the result.
S= 4 4 3 4 2
0 0 4 4 4
0 4 3 3 0
t = wholesale retail
$840 $1100
$1200 $1350
$1450 $1650
$2650 $3000
$3050 $3200
ST =
29210 33150
28600 31400
17100 19350
choose one of the following that best describes the above:
a) The entries represent the profits the retail outlets can get for each model of computer.
b) The entries represent the inventory quantities at the three outlets.
c) The entries represent the wholesale and retail values for each model if the outlets were combined.
d) The entries represent the wholesale and retail values of the inventories at the three outlets.
