Cost Confirmed

So, my dad got home from vacation and I showed him my new headphones. He said that he used to have a pair exactly like them, just green, back when he was a teenager. He paid $13 for his and earned at his job $1.75/hr. that equals out to about ten hours of work, so, in terms of purchasing power, the equivalent would be going out and buying a $70-$80 pair of headphones.
