My question is: Ali and Ernie lined up boxes to make circles. Ali used 8 boxes to make each of his circles and Ernie used 10 for his. If they had 80 boxes to begin with and Ali makes 5 circles, how many circles can Ernie make? Your thoughts:
Ali made 5 circles with 8 boxes each so he used 5 * 8 = 40 boxes. There were 80 boxes to start with so now there are 80 - 40 = 40 boxes left. Ernie used 10 boxes to make one circle so with 40 boxes he can make 40 / 10 = 4 circles. The final answer: 4.
