Answer :
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
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
