Final answer:
Peter should choose Rogers for a 5-month contract, as it offers a monthly rate of $25.50 without any additional yearly fees.
Step-by-step explanation:
In choosing between Rogers and Bell for a 5-month voice plan, the decision on minimizing costs. Rogers offers a straightforward $25.50 per month plan, resulting in a total expense of $127.50 over the 5-month period. On the other hand, Bell presents a more nuanced pricing structure, with a monthly fee of $18 and an additional yearly charge of $20. When calculated for the 5-month duration, the total cost for Bell comes to ($18/month * 5 months) + $20 (yearly fee) = $98.
Despite the initial appearance of a yearly fee, Bell proves to be the more economical option for a short-term contract. The lower monthly rate offsets the impact of the yearly fee when spread across the 5-month period. Therefore, Peter should choose Bell if he only needs a 5-month voice plan. This analysis underscores the importance of considering the specific duration of the contract and factoring in all associated costs to make an informed decision based on individual needs and budget constraints.
