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.
Let $x = the amount the apprentice makes.
>>A journeyman makes 200% of what an apprentice makes<<
The journeyman makes 200% of x, which is 2x
>>a master makes 250% of what a journeyman makes<<
The master makes 250% of 2x, which is 2.5(2x) = 5x
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.
