Question 1147722
.
<pre>

Let x = what the apprentice makes, in dollars.


Then the journeyman makes 2x dollars, and the master makes 2.5*(2x) = 5x dollars.


An equation for the total is


    x + 2x + 5x = 5600   dollars.


Simplify and solve for x


    8x = 5600

     x = {{{5600/8}}} = 700 dollars.


<U>ANSWER</U>.  700, 1400 and 3500 dollars for the apprentice, the journeyman and the master, respectively.
