18. A manager of a deli gathers data about the number of sandwiches sold based on the number of customers who visited the deli over several days. The table shows the data the manager
collects, which can be approximated by a linear function.
Customers 104 111 170 199 163 131
Sandwiches 70 74 114 133
109 90
If, on one day, 178 customers visit the deli, about how many sandwiches should the deli
manager anticipate selling?
[
A 119 sandwiches
B
124 sandwiches
с
178 sandwiches
D
253 sandwiches

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
