At a park, 96 brown-bag lunches were given out in thirty minutes. If 29 bags remain and x represents the starting number of brown-bag lunches, which equation could be used to determine the value of x?
There were 125 bags to start with. Explanation: Let x be the number of lunches to start with. 96 were given out, so x - 96 remain. As we have 29 left, we know that x - 96 = 29 So x = 29 + 96 = 125
