Answer:

Delaney has 36  books and 24 movies currently

Step-by-step explanation:

Given:

Delaney has 4 times as many books as she has movies.

she buys 15 more movies

Ratio of   movies to books =  2:3

To Find:

The number of  books and movies she is having currently = ?

Solution:

Let the number of movies be x

Then the number of books is 4x

After she buys 15 books, the number of books will be

x+15

Now the ratio of movies to books is 2 : 3

\frac{2}{3} = \frac{x+15}{4x}

On solving

3 \times(x+15) = 2 \times 4x

3x+45 =8x

45 =8x-3x

45 =5x

x =\frac{45}{5}

x = 9

The number of book is

=> 4 \times x

=> 4 \times 9

=> 36

The number of movies is

=>x + 15

=>9+15

=> 24
