Elgin battery manufacturers had sales of $1,000,000 in 2015 and their cost of goods sold is $700,000. selling and administrative expenses were $100,000. depreciation expense was $80,000 and interest expense for the year was $10,000. the firm's tax rate is 30 percent. what is the dollar amount of taxes paid in 2015?

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

i found two solutions,   n = 2 • ± √3 = ± 3.4641
