Question 766666
A crew consists of one apprentice, one journeyman, and one master carpenter. The crew receives a check for $6400 for a job they just finished. A journeyman makes 200% of what an apprentice makes, and a master makes 250% of what a journeyman makes.  How much does each receive.
<pre>
Let $x = the amount the apprentice makes.
</pre>
>>A journeyman makes 200% of what an apprentice makes<<
<pre>
The journeyman makes 200% of x, which is 2x
</pre>
>>a master makes 250% of what a journeyman makes<<
<pre>
The master makes 250% of 2x, which is 2.5(2x) = 5x

{{{(matrix(4,1,

What, the, apprentice,makes))}}}{{{""+""}}}{{{(matrix(4,1,

What, the, journeyman,makes))}}}{{{""+""}}}{{{(matrix(4,1,

What, the, master,makes))}}}{{{""=""}}}{{{6400}}}

x + 2x + 5x = 6400
         8x = 6400
          x = 800

So the apprentics makes $800

The journeyman makes 2x, which is 2($800) = $1600

The master makes 5x, which is $4000.
