jason received a $50 gift certificate for his birthday. he wants to buy a dvd and a poster from a media store. (assume that sales tax is included in the prices.) write and solve a linear inequality to show how much he would have left to spend after making these purchases.
all dvd's only $14.95
all cd's only $11.25
all posters only $10.99

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
