both 15 and 16. having trouble solving

QUESTION 15 Based on the information provided in questions 3 A, B and C, what is the Expected Monetary Value of the best decision? QUESTION 16 4. The Montefiore North Medical Center in New Rochelle, NY has developed a multiple regression line for forecasting the expected number of deaths from strokes (Y) as a function of 1)X1, time in minutes from the onset of symptoms until first seeing an Emergency Room physician and 2) X2, the time, in tenths of an hour, of treatment with TP4, a clot-busting pharmaceutical, that is most effective in the first 2 hours from onset of symptoms and decreases with time beyond 2 hours. The equation is as follows: Y = 0.75 +0.01X1 + 0.20 (X2-2.00) What are the expected number of deaths due to stroke for patients who arrive at the ER and see a physician 20 minutes after the onset of symptoms and receive administration of TP4 2 hours and 15 minutes after the onset of symptoms?
