Answer:

Option C

Step-by-step explanation:

Given that there is an annual increase in cost

If rate of increase is r then we have

C(1+r) for I year and for II year C(1+r)^2 etc

Hence for t years

A = C(1 + r)^t

Option A is wrong because exponent t should be for 1.05

Option B is wrong because here 1-r is done instead of 1+4

Option C is correct because r =0.05 and C=3.60 is correctly substituted

Option D is wrong because 1 is not added to r

SO finally only option C is right
