    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).

  2. Sam Miller, Anastasia Gabriel

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

  3. Kelly T. & Madison S.

    Option C because you will save more money because it is cheaper.

  4. Noah Cruz

    Option C because you would be paying less over time.

  5. Joelle H

    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.

  6. Katherine Almy

    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

  7. Kylie P

    Option C because it is cheaper over time

  8. jena b

    Option C because you’re paying less

  9. Gabriel A.

    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.
