Answer 2

Problem Analysis

We are given the following information: - The sixth graders repaired 4 times more chairs than tables. - The fifth graders repaired an equal number of chairs and tables. - The number of chairs repaired by the sixth graders is 11 less than the number of chairs repaired by the fifth graders. - The number of tables repaired by the sixth graders is 7 more than the number of tables repaired by the fifth graders.

We need to determine the number of chairs and tables repaired by the sixth graders.

Solution

Let's assume the number of chairs repaired by the fifth graders is x. Since the sixth graders repaired 4 times more chairs than tables, the number of tables repaired by the sixth graders would be x/4.

According to the given information, the number of chairs repaired by the sixth graders is 11 less than the number of chairs repaired by the fifth graders. So, the number of chairs repaired by the sixth graders would be x - 11.

Similarly, the number of tables repaired by the sixth graders is 7 more than the number of tables repaired by the fifth graders. So, the number of tables repaired by the sixth graders would be (x/4) + 7.

To find the total number of chairs and tables repaired by the sixth graders, we add the number of chairs and tables repaired by the sixth graders: Total = (x - 11) + ((x/4) + 7).

Now, we can solve this equation to find the value of x.

Calculation

Let's solve the equation to find the value of x:

Total = (x - 11) + ((x/4) + 7)

Simplifying the equation: Total = x - 11 + (x/4) + 7

Combining like terms: Total = (5x + x + 4(7) - 11) / 4

Simplifying further: Total = (6x + 25) / 4

To solve for x, we can multiply both sides of the equation by 4: 4 * Total = 6x + 25

Now, subtract 25 from both sides: 4 * Total - 25 = 6x

Finally, divide both sides by 6: x = (4 * Total - 25) / 6

We can use this equation to find the value of x and then calculate the number of chairs and tables repaired by the sixth graders.

Answer

To find the number of chairs and tables repaired by the sixth graders, we need to know the value of Total. Please provide the value of Total so that we can calculate the answer for you.
