At the grocery store sam bought a gallon of milk for $1.99, a loaf of bread for $2.39, lunch meat for $6.45, and a pound of cheese for $4.50 what was the total sam paid for these items

Sam paid $15.33

Step-by-step explanation:

1.99 + 2.39 + 6.45 + 4.50= $15.33

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

the answer is b.)
