Question

If I bought 3 books and an album for 25 dollars but he album was double the money of each of the three books how much did the album cost?

 

Answer 1

Let b = price of a book

Then 2b = price of the album

 

3 books plus album = 25

 

3b + 2b = 25

5b = 25

b = 5

 

Books cost $5 each and the album cost $10
