Answer 1

good question I don't know

Answer 2

Thank you for asking this question. Here is your answer:

x can be the cost of a chocolate

y can be the cost of a milkshake

and z can be the cost of cake

We will make 2 equations now,

2x + 3y + 4z = 190 (equation 1)

4x + 8z = 320 (equation 2)

Now we will Multiply the equation 1 by 2.

And subtract 1 by 2

The final answer would be 10
