Elise has been selling her Dad's collection of 250 books for three years. Each book sells at 20$, and she sold twice as many books in the first year as she has sold in the current year. There are currently 50 unsold books, and her sales number this year is 45. What's the total amount of money she earned in the second year?

How many books did Elise sell in the first year? ** If her sales in the current year are 45, she sold 45*2 = <<45*2=90>>90 books in the first year.
How many books did Elise sell in the first and current year? ** The total number of books sold in the first and current year is 90+45 = <<90+45=135>>135.
How many books did Elise sell in the second year? ** The total number of books sold in the second year is 250 of the original number of books - 135 sold books - 50 unsold books = <<250-135-50=65>>65 books.
How much money did Elise earn in the second year? ** If each book sells at 20$, then she earned 20*65 = $<<20*65=1300>>1300 in the second year
