The reward of CZK 4,220 was divided among 3 workers in such a way that the second received CZK 400 more than the first, and the third received 30% more than the second. How much did each get?

Correct answer:

a =  1000 Kc
b =  1400 Kc
c =  1820 Kc

Step-by-step explanation:

s=4220 Kc r=100%+30%=1+10030=1.3  b = 400 + a c = r b=r (400+a) a+b+c=s  a+(400+a)+r (400+a)=s a+(400+a)+1.3 (400+a)=4220  3.3a=3300  a=3.33300=1000  a=1000=1000 Kc
b=400+a=400+1000=1400 Kc
c=r b=1.3 1400=1820 Kc
