The cost of my algebra book is 200% of that of my geometry book. The cost of my geometery book is 4/3 that of my calculus book. If my calculus book costs $21, how much do all 3 books cost together?

Let the Geometry book price = P

The Algebra book = 2P

And the Geometry book = (4/3)Calculus book

 

The geometry book costs (4/3)*21 = $28

The Algegra book costs 2(28) = $56

 

So

 

21 + 28 + 56  =  $105
