Answer:
Pushing from the same direction: 343 N
Pushing from opposite directions: 171 N
Explanation:
If Dani and Gina are pushing in the same direction then you would add up the forces they are pushing with since the force is applied in the same direction.
257N+86N=343 N
If Dani and Gina are pushing in the opposite direction then you would subtract the forces they are pushing with because they are going against each other.
257N-86N=171 N
Hope this helped! :)
