Pants cost $18.50 and it is 25% off, what is the cost?

Rounded to $13.88

Step-by-step explanation:

We know that 25% is 1/4 of 100% so you multiply $18.50 by 1/4 and get 4.625. Then you subtract 4.625 from 18.50 and this gives you $13.875.

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
