Question

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?

Answer 1

Answer:

The first worker produced 46 parts and the other one 40 parts.

Explanation:

First, according to the information you have these equations:

a+b= 86

a= 1,15b

You have to replace the second equation in the first one to get the value of b:

1,15b+b= 86

2,15b=86

b= 86/2,15= 40

Then, replace the value of b in a= 1,15b:

a=1,15*40 = 46

Answer 2

86 parts = x + (x * 1.15)
86 = 2.15x
x = 40 parts and 1.15x = 46 parts
