An item on sale costs 30% of the original price if the original price was $50 what is the sales price

$35

Step-by-step explanation:

50 * .3 = 15

50-15 = 35

$15.00

Step-by-step explanation: 30% of $50 is $15 because .3 times 50 is 15.

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
