Answer:
457.25
1636.4
Explanation:
To find this you need to figure out what the probability of you needing it is. I believe that you then need to see how much you will pay with that. ex:1050 with only 32% chance that you will need it. So 336. 225 but only 45 %, so 121.25.
1,580 guarantied. 24. 32.4. Add all these together you get 1636.4.
