You got sick with a flu and you have two approaches of treatment: 1) buy a chicken soup and ibuprofen that would cost $20 for a 7-day supply; flu lasts 7 days and your quality (utility) weight is .55; 2) take Tamiflu that costs $175 for a 7-day supply; flu lasts 7 days and quality (utility) weight is .6. Calculate incremental cost-effectiveness ratio of the 2nd strategy relative to the 1st.
