Homework Equations

The Attempt at a Solution

T-W_a=0
W=mg=-186.6
T=186.6
T-Q-fs=0
186.6-Q-fs

fs=uN
N=60+147=207
fs=82.8
186.6-Q-82.8=0
Q=103.8
what is wrong??

wait so should I take the direction of friction to the right? 82.8+186.2=269 .. but that also isn't in the choice list

Edit: wait I have things to two significant figures right? so is 270 the right answer?
