At full price, Melvin would pay 1.6791.6791, point, 679 dollars per liter of gasoline. Using his loyalty card, Melvin only pays 1.4391.4391, point, 439 dollars per liter. How much less does Melvin pay per liter using his loyalty card?

dollars

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

ab will be equal to

answer: 100
