What was the question for this implicit rationale, and corresponding answer?
Dan gets 5 * 12 = 60 golf balls. Gus gets 2 * 12 = 24 golf balls. In total they purchase 60 + 24 + 48 = 132 golf balls.
 The answer: 132
The question: The batting cage sells golf balls by the dozen. They charge $30 for 3 dozen. Dan buys 5 dozen, Gus buys 2 dozen, and Chris buys 48 golf balls. How many golf balls do they purchase in total, assuming 12 golf balls are 1 dozen?
