Consider the question. For Halloween, Taquon, Mack and Jafari put their candy together and they had 418 pieces of candy. If Taquon and Mack each had 171 pieces of candy, how many pieces of candy did Jafari start with?
 What is the step-by-step reasoning process to arrive at the answer: 76?
Taquon + Mack = 2 * 171 = 342 pieces. 418 - 342 = 76 pieces. Jafari started with 76 pieces of candy.
