to estimate your average monthly salary, divide your year salary by the number of months in a year. write and solve an equation to detrain your yearly salary when your average monthly salary is 5,460

First, we'll define our variable.

S - yearly salary

Second, we'll write our equation.

Because there are 12 months in a year, our equation (dividing yearly salary by the number of months in a year) will be:

S/12 (yearly salary divided by 12, the number of months in a year.)

Therefore, if you are earning 5,460 in a year, your average monthly salary is 5,460/12, which is equal to 455

The average yearly salary is 455.
