The present value of the costs of carrier A = $ 200 + $ 60 1.041 + $ 60 1.042 + $ 60 1.043 + $ 60 1.044 + $ 60 1.045 + $ 60 1.046 + $ 60 1.047 + $ 60 1.048 + $ 60 1.049 + $ 60 1.0410 + $ 60 1.0411 + $ 60 1.0412 + $ 60 1.0413 + $ 60 1.0414 + $ 60 1.0415 + $ 60 1.0416 + $ 60 1.0417 + $ 60 1.0418 + $ 60 1.0419 + $ 60 1.0420 + $ 60 1.0421 + $ 60 1.0422 + $ 60 1.0423 + $ 60 1.0424
The present value of the costs of carrier A = $ 1,114.82
The present value of the costs of carrier B = $ 100 + $ 70 1.041 + $ 70 1.042 + $ 70 1.043 + $ 70 1.044 + $ 70 1.045 + $ 70 1.046 + $ 70 1.047 + $ 70 1.048 + $ 70 1.049 + $ 70 1.0410 + $ 70 1.0411 + $ 70 1.0412
The present value of the costs of carrier B = $ 1,513.91
Thus you should choose carrier A because the present value of the costs of carrier A is less than the present value of the costs of carrier B.
