How many stamps are on the first 10 pages? ** There are 30 x 5 = <<30*5=150>>150 stamps on each of the first 10 pages.
How many stamps are in the first 10 pages? ** So she has a total of 150 x 10 = <<150*10=1500>>1500 stamps in the first 10 pages.
How many stamps are in the rest of the pages? ** There are 50 - 10 = <<50-10=40>>40 pages that have 50 stamps each.
How many stamps are in the remaining 40 pages? ** There is a total of 40 x 50 = <<40*50=2000>>2000 stamps in the remaining 40 pages.
How many stamps are in Stella's album? ** Therefore, Stella has 2000 + 1500 = <<2000+1500=3500>>3500 stamps in her album.
