An executive in an engineering firm earns a monthly salary plus a Christmas bonus of 7500 dollars. If she earns a total of 82100 dollars per year, what is her monthly salary in dollars?

Solution

Toal salary per year = 12 x monthly salary + Christmas bonus.

so, 82100 = 12* monthly salary + 7500

or, 82100 - 7500 = 12* monthly salary ( subtracting 7500 from both sides)

or, 74600 = 12* monthly salary

so, monthly salary = 74600/12 = 6216.67

So here monthly salary is approximately 6216.67 dollars.
