## 8M- REASONS FOR STRIKING- PART II: THE MATHEMATICAL PROBLEM

“Women work more every day, by an average of TWO hours, ONE minute and THIRTY NINE seconds, to make the same as their male colleagues, according to the gender salary gap of 21%”

How did we get to know that women have to work 2h1’39” more than men to earn the same?
First of all, someone invested their time in comparing salaries between men and women in different jobs, and concluded that women earn 21% less than men for doing the SAME tasks.
If we use equations, we can easily check the given overtime.

To simplify the calculation, we solved the problem using 20% instead of 21%.

We defined the following variables:
Xw: women´s salary per hour
Xm: men´s salary per hour
Sw: women´s daily salary
Sm: men´s daily salary
t: overtime
We suppose that both, women and men, work 8 hours a day.
Sw = 8 Xw
Sm = 8 Xm
Xw = 0.8 Xm  (because a woman makes 20% less per hour)
To make the same, a woman must work 8+t hours
(8+t) 0.8 Xm = 8 Xm
The solution of the equation is t=2

Remember that “t” is the OVERTIME...that means that a woman should work 10 hours a day to earn the same as a man...DO YOU REALLY THINK IT IS FAIR?
