Manny’s Music Rental charges a fee of $40 plus $25 per month to rent a saxophone. Sid’s Saxophones charges $25 plus $30 per month to rent the same saxophone. Write the system of equation the represents the cost of Sarah's rental shop and another equation for David's rental shop.

Manny's Music Rental:  y = 40 + 25x

Sid's Saxophones:   y = 25 + 30x

Step-by-step explanation:

Let x = number of months

Let y = total cost of renting a saxophone

Manny's Music Rental:  y = 40 + 25x

Sid's Saxophones:   y = 25 + 30x

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

domain = x values

range = y values
