4. Andrija lent 54 kuna to his friends. He lent Mark ten kuna more than Ivan, and he lent Goran twice as much as Mark. How much money did he lend to each of his friends?
4. Ivan...
    Marko... + + 10
    Goran... a+ a+10+10
```

a+ + +10+ם+口+10+10=54

1 POINT

4口+30=54 1 POINT

4口=24 1 POINT

a=6

So, Ivan borrowed 6 kn. 1 POINT

Marko borrowed 6 kn + 10 kn = 16 kn, and Goran borrowed 2 * 16 = 32 kn. 2 POINTS

TOTAL 6 POINTS
