Question 1033234: An executive in an engineering firm earns a monthly salary plus a Christmas bonus of 6600 dollars. If she earned a total of 90300 dollars per year, what is her monthly salary in dollars.
Answer by Theo(13342)   (Show Source): You can put this solution on YOUR website!
she earned 90300 for the whole year.
this includes the christmas bonus of 6600.
subtract that from 90300 and you get a salary of 83700 for the year.
divide that by 12 and you get a monthly salary of 6975.
to calculate her yearly earnings, you would multiply the monthly salary by 12 and then add the christmas bonus on top of that.
12 * 6975 + 6600 = 90300.
put the commas where they belong and her monthly salary is 6,975 dollars.

algebraically, you would solve this as follows:

let x = her monthly salary.
her yearly salary is therefore 12*x.

your equation becomes 12*x + 6600 = 90300
subtract 6600 from both sides of the equation to get 12*x = 83700.
divide both sides of the equation by 12 to get x = 6975.
