He writes 30/3=<<30/3=10>>10 normal letters

Each letter is 20/10=<<20/10=2>>2 pages

So that is 2*10=<<2*10=20>>20 pages

His long letter takes 2*10=<<2*10=20>>20 minutes per page

So it is 80/20=<<80/20=4>>4 pages

So he writes 20+4=<<20+4=24>>24 pages

Steve writes a letter every 3rd day to his friend.  He spends 20 minutes writing the letters.  It takes 10 minutes to write 1 page.  He also writes a long letter at the end of the month which he puts more thought into.  It takes twice as long per page but he spends 80 minutes writing.  How many pages does he write a month?
