Question 1187443
.
Larry spent $480 of his salary on a suitcase and 1/4 of the remaining
amount on a watch. He then had 1/3 of his salary left. How much was his salary?
~~~~~~~~~~~~~~~~~~~


<pre>
Let x be his salary, in dollars.


Write an equation as you read the problem


    x - 480 - {{{(1/4)*(x-480)}}} = {{{x/3}}}.


To solve, multiply both sides by 12.  You will get


    12x - 12*480 - 3*(x-480)  = 4x

    12x - 12*480 - 3x + 3*480 = 4x

    12x - 3x - 4x             = 12*480 - 3*480

          5x                  =     4320

           x                  =     4320/5 = 864.


<U>ANSWER</U>.  His salary is  $864.
