Answer:
Apprentice=$800
Journeyman=$1600
Master=$2400
Step-by-step explanation:
We have that all the crew won a total of $4800 then it is the salary of the apprentice, the journeyman and the master carpenter. It say that the journeyman makes 200% of the apprentice, then it means that the journeyman won the double of the apprentice. The master won 150% of what a journeyman, it means that the master won 1.5 of the salary of the journeyman.
With this information we can write the next set of equations.
Using the second equation in the third equation we can know how much won the master in terms of the salary of the apprentice, then:
With this we could rewrite the first equation as:
Then the aprentice earn $800, the journeyman $1600 and the master $2400
x=0 or x =3
for x = 0 y = 4
