7) A large crate has a mass of 120 kg and sits on a horizontal floor. You push on the crate with a horizontal force of 550 N, but the crate does not move. The coefficient of static friction between the crate and the floor is 0.6. What is the magnitude of the static frictional force acting on the crate? (а) 0 N (b) 706 N (c) 1176 N (d) 330 N (е) 550 N

Question
Hello, need help with this problem. I got 706N but I'm not sure if that is the right answer.
Here is my work:
Weight of the crate = 120(9.8) = 1176
F = 0.6(1176)
F = 705.6 N
