Answer 1

so which part are you having problems with..?

Answer 2

the whole thing. i dont get it at all.

Answer 3

ok... so make a table of values

t: 0 : 1: 2: 3: 4: :5 : 6: 7: 8
-----------------------------------
s: 15 : 37.4 : 46.6 :

so keep substituting values of t to calculate s.

plot the points on the number plane

and extending the table you will know the value of s when t = 8.

remember that the value of s needs to be multiplied by 1000 to get the dallar value... so that eliminates A and C as answers

hope it helps
