Answer 1

child- 10 lei

banana-b  apple-a ----> b+a=5 lei

3 pens- 3p  notebook-n ----> 3p+n=5 lei(ramasi)+2 lei

   it says here that the notebook is 2 lei/zice aici ca caietul este 2 lei

====>3p=5 lei => pen=1,(6) lei / 1,6 lei  

 2p=1,6 lei+ 1,6 lei/ 1,(6) lei x 2 = 3,6 lei (in cazul in care p este 1,6)
