Which equation models this problem?
susan paid $48.80 for eight dish towels. what is the unit price, p, per towel?
a. 8p= 48.80
b. 48.80p = 8
c. p/8 = 48.80
d. p/48.80 = 8

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
