Using a system of equations, it is found that her normal week is of €285.
What is a system of equations?
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the variables are given as follows:
- Variable x: Her normal hours.
- Variable y: Her time and a half hours.
The first equation, considering the first sentence, is given by:
x + 8y = 375.
The second equation, considering the second sentence, is given by:
x + 4y = 330.
Then the system is:
Multiplying the second equation by -2, the system is:
Adding the equations, we have that her normal week is given by:
x = 660 - 375 = €285.
