Calculating the Number of Machines in the Workshop

To calculate the number of machines in the workshop, we can use the information provided.

Given: - 29% of all machines in the workshop were repaired. - After the repair, 142 machines remained.

Let's denote the total number of machines in the workshop as x.

The number of machines repaired is 29% of x, which can be expressed as 0.29x.

The number of machines remaining after repair is 142.

We can set up the equation: 0.29x + 142 = x

Solving for x

To solve for x, we can first isolate the variable on one side of the equation.

0.29x + 142 = x 0.29x = x - 142 0.29x - x = -142 -0.71x = -142

Now, we can solve for x: x = -142 / -0.71 x = 200

Answer

The total number of machines in the workshop is 200.
