Summerjob

Three students participated in the summer job. Altogether they earn 1780, -. Peter got a third less than John, and Paul got 100 more than Peter. How much earn every one of them?

Correct answer:

a =  480
b =  720
c =  580

Step-by-step explanation:


a+b+c=1780
a=b-b/3
c=100+a

a+b+c = 1780
3a-2b = 0
a-c = -100

a = 480
b = 720
c = 580
