An electrician earns 100 dollars for a project installing light fixtures. she must pay for the light fixtures herself and they cost 2 dollars and 50 cents each at the hardware store. create an equation to represent her profit from the project. let x represent the number of light fixtures and y represent her total profit (the amount of money she has left over after paying for the light fixtures).

look a the sides they are perpendicular

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

the answer is 2/54
