    Answer: 160 songs.

    Step-by-step explanation:

    75% hip hop music   –    120 songs

    100% all music          –     x songs

    Let’s write the proportion:

    \dfrac{120}{75} =\dfrac{x}{100} \\\\75x=120 \cdot 100\\75x=12000\\75x : 75 = 12000 : 75\\x = 160

    Thus, Landon have 160 songs in his music library.
