Dave receives a salary of $200 a week plus a commission of 10% of his weekly sales. an equation 4072-03-01-04-00_files/i029.jpg represents dave’s weekly earnings. the y-intercept is dave’s base salary. the slope of the line is his commission.
write an equation representing dave’s weekly earnings. if dave sells $1500 of goods for one week, what is his salary for the week?
a.
$13,000
b.
$350
c.
$1520
d.
$130

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
