I am very confused on how to solve for this it's my third attempt on asking for help. I don't know if it's v=c/b ? Can someone please help me solve this?

Assume that health-related quality of life over 5 years for diabetic women and treated women represented in the following table. How much would society be willing to pay for the treatment assuming threshold for cost per QALY of $40,000. You can also assume zero discount rate and probability of survival 1 for all these years. (Hint: calculate gain in QALYs first). Show your work.

1 0.8 0.9

2 0.8 0.9

3 0.7 0.9

4 0.8 0.9

5 0.6 0.9
