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?
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
