Ответ:

613,70 руб. стоили остальные товары

Пошаговое объяснение:

Всего потратил 1805 руб.

учебники 57% от общей суммы,значит на учебники потратили

1805*57/100=1028,85 руб.

ручка 9 % от общей суммы, значит на ручку потратил

1805*9/100= 162,45 руб.

Остальные товары стоили

1805-1028,85-162,45= 613,70 руб.
