Answer 2

Problem Statement

You bought 19 buns. The adults ate some buns, leaving three buns for your daughter and the same amount for your son. How many buns did the adults eat?

Solution 1: Using Algebraic Expression

Let's assume that the number of buns eaten by the adults is 'x'. According to the problem statement, the adults left three buns for your daughter and the same amount for your son. So, the equation representing the given information is:

x + 3 + x + 3 + x = 19

Simplifying the equation, we get:

3x + 6 = 19

Subtracting 6 from both sides of the equation, we have:

3x = 13

Dividing both sides of the equation by 3, we find:

x = 13/3

Since we cannot have a fraction of a bun, we need to round the answer to the nearest whole number. Therefore, the adults ate approximately 4 buns.

Solution 2: Using Arithmetic

We know that the adults left three buns for your daughter and the same amount for your son. So, the total number of buns left for both children is 3 + 3 = 6.

To find the number of buns eaten by the adults, we subtract the number of buns left for the children from the total number of buns:

19 - 6 = 13

Therefore, the adults ate 13 buns.

Conclusion

Using two different methods, we have determined that the adults ate either 4 buns or 13 buns, depending on the interpretation of the problem.
