Franco listens only to Symphonic music or Dolly Parton. Franco purchases 12 Symphonic music downloads and 24 downloads by Dolly Parton per month. He would forgo downloads by Dolly for the Symphonic downloads at the rate of 3:1 whenever he has more Dolly units than Symphonic ones. But he would forego only 1 unit by Dolly per Symphonic music unit when the opposite is true.
