The family paid a total of CZK 31,030 for two children's, one men's and one women's bike. How many crowns did each round cost?

Correct answer:

d =  9570 Kc
p =  8700 Kc
c =  6380 Kc

Step-by-step explanation:

p1=10%=1+10100=1.1  d=p1 p=9570 Kc c=dd/3 2c+p+d=31030 d=1.1 p c=dd/3 2c+p+d=31030  d=1.1 p c=dd/3 2 c+p+d=31030  d1.1p=0 3c2d=0 2c+d+p=31030  c=6380 d=9570 p=8700
