Tv circuit has 30 large-screen televisions in a warehouse in erie and 60 large-screen televisions in a warehouse in pittsburgh. thirty-five are needed in a store in blairsville, and 40 are needed in a store in youngstown. it costs $19 to ship from pittsburgh to blairsville and $23 to ship from pittsburgh to youngstown, whereas it costs $21 to ship from erie to blairsville and $26 to ship from erie to youngstown. how many televisions should be shipped from each warehouse to each store to minimize the shipping cost? hint: if the number shipped from pittsburgh to blairsville is represented by x, then the number shipped from erie to blairsville is represented by 35 − x.

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

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
