The markup on a restaurant meal is 50%. A meal costs $7.30 to produce, How much will the customer be charged before tax and tip?

7.30*1/2=7.30/2=2.65

7.30+3.65=10.95

$10.95

here the number -5 is all of the following except a rational number.

step-by-step explanation:

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
