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?

To determine the value of x, we need to write an equation based on the given information. Let's break down the information we have:

- 96 brown-bag lunches were given out in thirty minutes.
- 29 bags remain.

Since x represents the starting number of brown-bag lunches, we know that the difference between the starting number and the number of bags given out should equal the number of bags that remain.

The number of bags given out can be calculated by subtracting the number of remaining bags (29) from the starting number (x):

Number of bags given out = x - 29.

Since 96 brown-bag lunches were given out, we can set up the equation:

x - 29 = 96.

Therefore, the equation that could be used to determine the value of x is x - 29 = 96.

x - 96 = 29

Note that it doesn't matter how long it took to hand them out. Just extra data to confuse you. Always see what the question is before trying to use all the data.
