<p>Can anyone help me with the answer to number 9 on section 9 of practice test 1 in the blue book? I know its a decently easy problem but I keep getting stuck. Can some one edify me please?</p>
<p>Plug in answer choices.
Say P = 3
2(3) + 7 / 5 should give a remainder of 3 and it does. Just backsolve.</p>
