Alaptop has a listed price of
$683.99
before tax. if the sales tax rate is
6.25%
, find the total cost of the laptop with sales tax included.
round your answer to the nearest cent, as necessary.

∞ this is your sign

step-by-step explanation:

their are no angles. sorry cant .

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

you divide them and then you get the answer i took this class this year
