Two different chemotherapy regimens can be used for the treatment of breast cancer. The treatment with doxorubicin is known to show a remission rate 40% of the time. This treatment costs $1,000. The other treatment, with docetaxel, shows a remission rate 25% of the time and costs $850. The two treatment plans are as follows:
Plan A: Treatment with doxorubicin—if not effective, treatment with docetaxel.
Plan B: Treatment with docetaxel—if not effective, treatment with doxorubicin.
If you are the patient, which statement is the best choice?
A. Based on the probability of overall remission rate, plan A should be selected over plan
B. Based on the probability of overall remission rate, plan B should be selected over plan
C. Based on the cost of the first treatment alone, plan A should be selected over plan B.
D. Based on the overall cost of treatment, plan B should be selected over plan A. E. Based on the probability of survival rate and the cost of treatment, both plans are equivalent, so either can be selected.

I think the answer would be C. based on the cost of the treatment alone, plan A should be selected over plan B

If we count the cost and probability of remission, the cost of per 1 % remission with plan A is $ 25 , while the cost of per 1 % remission with plan B is $ 34

hope this helps
