22.00+27.51+21.33+22.95= please show me how you got that answer

asap plz help 50 points

93.79

Step-by-step explanation:

22.00 + 21.33 = 43.33

22.95 + 27.51 = 50.46

43.33 + 50.46 = 93.79

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
