Answer 3

Calculating the Number of Chairs and Stools in the Kitchen

To solve this problem, we can use algebra to represent the given information and then solve for the number of stools.

Let's denote: - T as the number of stools - S as the number of chairs

Given: - Each stool has 3 legs - Each chair has 4 legs - There are a total of 38 legs when people with 2 legs each are seated on all the stools and chairs

We can create the following equation based on the given information: 3T + 4S = 38

Solving for the Number of Stools

To solve for the number of stools, we can use the equation 3T + 4S = 38 and the fact that people with 2 legs each are seated on all the stools and chairs.

We can start by substituting the value of S from the equation 3T + 4S = 38: 4S = 38 - 3T S = (38 - 3T)/4

We know that the number of stools and chairs should be whole numbers, so we can try different values of T to find the appropriate number of stools.

Let's start by substituting T = 1, 2, 3, and so on until we find a whole number solution for S.

Finding the Number of Stools

Substituting T = 1: S = (38 - 3*1)/4 S = (38 - 3)/4 S = 35/4 (not a whole number)

Substituting T = 2: S = (38 - 3*2)/4 S = (38 - 6)/4 S = 32/4 S = 8 (whole number)

Conclusion

When T = 2, the number of stools is 2 and the number of chairs is 8. Therefore, there are 8 chairs in the kitchen.
