Question

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?

Answer 1

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  

Answer 2

Answer:

x - 96 = 29    is the CORRECT answer
