The first month's dues will be used to rent a film about computer-related careers, to purchase a reference book, and to buy refreshments for the next meeting. If 1/2 of the money is spent on her film, 1/4 of the remainder is used for refreshments, and $7.50 is spent on the book, how much money will be spent?

1/2 = film

1/4*1/2 (1/8) = refreshments

3/4*1/2 (3/8) = $7.5 = book

 

7.5 * 8/3 = 20

 

So total = $20
