One model of microwave regularly sells for $214. It is on sale for 35% off.
The sales tax on it is 6%. Which is the
closest estimate to the final cost?

$143.45

Step-by-step explanation:

First you would want to know how much the sale takes off which is $74.9 off of the $214, then you subtract the $74.9 from the $214 which then equals, now you get $139.10 and find the tax of it you take 6% out of it which is $8.35, and now you get your answer of $143.45. Hope this helps.

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
