    Answer

    39 bills of 1$

    16 bills of 10$

    Step-by-step explanation:

    x-nr of $1

    y-nr of $10

    x*1+y*10=199

    x+y=55 , x=55-y

    so  I use the substitution method

    (55-y)*1+10y=199

    55+10y-y=199

    -55            -55

    9y=144

    y=144/9

    y=16

    so x=55-16

         x=39

    verify 16*10+39*1=160+39=199
