Elizabeth has 20 dollars and wants to buy pens and pencils. Each pencil costs $1.60 and each pen cost 2 dollars. How many pencils can she buy with her 20 dollars if she wants 6 pens?
Elizabeth spends 6*2 = <<6*2=12>>12 dollars on pens.
Elizabeth has 20-12 = <<20-12=8>>8 dollars to spend on pencils.
Elizabeth can buy 8/1.6 = <<8/1.6=5>>5 pencils.
