You and 2 friends have a job washing cars. you split the money you make so that you each get the same amount. on the first day, the earnings are $75. on the second day, the earnings are $84. on the third day, the earnings are $105. how much money will you each get for those 3 days?

answer: ur mum is gay

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
