    Answer: Robbie gas 253 movies and Joshua has 198 movies.

    Step-by-step explanation:

    Robbie owns 15% more movies then Rebecca. If Rebecca 220 movies, it means that the number of movies that Robbie has more than Rebecca is

    15/100 × 220 = 0.15 × 220 = 33

    Therefore, the number of movies that Robbie has is

    220 + 33 = 253 movies.

    Rebecca owns 10% more movies than Joshua. It means that the number of movies that Rebecca owns more that Joshua is

    10/100 × 220 = 0.1 × 220 = 22

    Therefore, the number of movies that Joshua has is

    220 – 22 = 198 movies

    Answer:

    thus Joshua has 200 movies  and Robbie 253 movies

    Step-by-step explanation:

    if Robbie owns 15% more than Rebecca , then he holds

    Movies of Robbie = (1+0.15)*Movies of Rebecca = 1.15 * 220 movies = 253 movies

    Then we know that Rebecca has 10% more than Joshua , therefore

    Movies of Rebecca = (1+0.10)*Movies of Joshua

    220 movies = 1.10 * Movies of Joshua

    Movies of Joshua = 220 movies/ 1.10 = 200 movies

    thus Joshua has 200 movies and Robbie 253 movies
