A grocer wanted to mix 19 liters milk of $2.2 with 1 kg cacao to make a mixture of hot chocolate. What should be the cost of milk, if the total mixture costed 3 dollars? Please write a equation and the answer.

there is no equation to this

Step-by-step explanation:

I think this is the

Equation: $3.00 - $2.20 = $0.80

$0.80

Step-by-step explanation:

This is the answer because:

1) Since 1 kg of cacao is $2.20 and the whole thing costed $3.00, all we hvae to do is subtract $3.00 with $2.20 to figure out what the milk costed which is 80 cents:

$3.00 - $2.20 = $0.80

Hope this helps! :D

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
