You are trying to decide between two mobile phone carriers. Carrier A requires you to pay

$210

for the phone and then monthly charges of

$66

for

24

months. Carrier B wants you to pay

$110

for the phone and monthly charges of

$68

for

12

months. Assume you will keep replacing the phone after your contract expires. Your cost of capital is

4.4%.

Based on cost alone, which carrier should you choose?
