: Ryan needs to buy a new hoodie. The ticket price of the hoodie was $65.00. After sales tax
was added, the final cost was $74.25. What
percent sales tax did Ryan pay on his hoodie?

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
