<prompt> Translate the following text to EnglishIkiwa WTP kwa kupunguza hatari ya vifo ni linear katika kupunguza hatari, basi WTP ya kupunguza hatari ya 50 kwa 100,000 inamaanisha WTP ya kupunguza hatari ya 500,000 kwa kupunguza hatari ya 100,000 ambayo ni mara kumi ya kupunguza hatari iliyopendekezwa katika utafiti.  <response>: If WTP for reductions in mortality risk is linear in risk reduction, then a WTP of 50 for a reduction of 1100,000 implies a WTP of 500 for a risk reduction of 110,000 which is ten times the risk reduction valued in the study.
