Gabriela has dinner at a cafe and the cost of her meal is $45.00. because of the service, she wants to leave a 15% tip. what is her total bill including tip?

$51.75 would be Gabriela’s total bill

Step by step explanation:

Cost of her meal is $45.00

Leaves a 15% tip

What is her total bill including tip = x

Step 1: Remove the percentage sign

15 / 100 = 0.15

Step 2: Amount of the tip * the total amount of bill

0.15 * 45  =  $6.75

Step 3: Total Bill including the tip:

$45 + $6.75  

= $51.75

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
