The expression 5x + 10 represents the amount of money in dollars the swim team earns by selling x school spirit shirts. a. If the team had to pay 2x+ 3 in expenses, write and simplify an expression to represent their profit.

b. If the team sold 25 shirts, what was
their profit?

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
