Imagine that you are a philatelist who collects dinosaur stamps from other countries. Solve the problems below to find out what it would cost to add these stamps to your collection.

• Look at the stamps.
• Solve the problems.

1. Julie has collected 600 Tanzanian dinosaur stamps. She bought 8 stamp-collecting albums to display her stamps. Each album can hold 72 stamps. Did she buy enough albums?
   
                                                                         
   
   
   
2. Nadia has her dinosaur stamp collection displayed in an album. The album has 25 pages. Each page contains 8 stamps. How many stamps are there in Nadia's collection?

Today I explored a Web site that showed collectors' stamps from Tanzania. I used the prices of the stamps to solve multiplication problems. For instance, I figured out that it would cost                                to buy 8 sets of Tanzania Gold stamps!
