In which direction does a bag at rest move when a force of 20 newton's is applied from the right?

The bag moves to the left.

This is because of Newton's third law of motion that states:

For every action force on a body, there is an opposite and equal reaction force.

Thus pushing the bag from the right makes it move to the left.

Correct

In the direction of the applied force
