Answer:
x=-8/(a-b)
Step-by-step explanation:

ax-bx=-8
Factor out x.
x(a-b)=-8
Divide both sides by a-b
x=-8/(a-b)
For this case we have the following table:
0 3
1 3.12
2 3.24
3 3.37
4 3.51
We can model the data with the following function:
y = (3) * (1.04) ^ x
Where,
3: initial cost
1.04: 4% annual increase in cost
x: number of years
Answer:
y = ab^x
