Two workers produced 86 parts during their working shift. The first worker produced 15% more parts than the second one. How many parts did each worker produce?

For the answer to the question above,

Let Worker 1 produces x parts

Let Worker 2 produces x+0.15x parts (0.15x is 15% of x)

Let us make the equation

x+x+0.15x=86

You can solve that for x, which will be the number of parts worker 1 produces

x=40

now we can solve for what worker 2 produces

40+0.15 (40) = 46 (**since there are two workers, you could also just subtract the parts produced by worker 1 from the total number)

Therefore,

worker 1 = 40 parts

worker 2 = 46 parts
