14. A
C=10+12h
I think one time fee is 10, the recurring fee is 12
15.B
c=2*12h=24h
initial value is going to be 0 because no one time fee, rate of change is 24
C=a*h+b(a is rate of change, and b is initial value)
For the answer to the question above, if P=R-E. If R is 25 million and E is 10 million, then 25-10=15, so you have 15 million as your profit. which makes B. <span>p = r - 10 $15 million I think the answer.
I hope my answer helped you.</span>
