Janice opened an art book that she had found in the library and found 5 drawings on the first page. After opening the first ten pages, she realized that the number of drawings on each page increased by five after every page. How many drawings were in the first five pages?
If the first page had 5 drawings, and the number of drawings on each page increased by five, the second page had 5+5 = <<5+5=10>>10
The total number of drawings in the first 2 pages is 5+10 = <<5+10=15>>15
On the third page, the number of drawings increased to 10+5 = <<10+5=15>>15
The first three pages have a total of 15+15 = <<15+15=30>>30 drawings.
The fourth page had 15+5 = <<15+5=20>>20 drawings.
There are 30+20 = <<30+20=50>>50 drawings on the first four pages.
The fifth page also had an extra 5 more drawings than the fourth page, totaling 20+5 = <<20+5=25>>25
For the first five pages, Janice saw 25+50 = <<25+50=75>>75 pages.
