    Option C, because it is a better deal from the other options because you will save money per month and the installments have a good amount (28).

    We believe option C is the best because it is the cheapest on out of the five other options that were given.

    I believe option C would be optimal. The payments are low and there is no initial fee along with device trade in after 12 months.

    Option D because it has more installments then option c even though it is the same price in the long run and also you can pay less for month if you pay 225 upfront

    Option D, you initially pay 30% of the total cost which is $225, this will then lower the rate to $18.75 for 28 installments. After 12 months, you receive the phone. This is better because you receive the phone at an earlier time, and pay less per installment.
