It is understandable to want another pet. Pets are wonderful. And to offer to pay for supplies shows true interest. But in the long run ( a lifetime of food, supplies and vet visits) $56 will pobably not go too far. Why don't you do some reserch on different types of pets, their needs, life spans, etc. and this will go a long way to help your dad see your true interest and willingness to get a pet within your means. Keep in mind that parents will be ultimately responsible for a pet that a child loses interest in (no offense meant, I am just trying to show their point of view) So when a parent says no it is not meant to hurt the child, it is meant to say they are not willing (or able) to make that commitment. (and I only mean "CHILD" in the sense of a person living under their roof who is under legal age. This could mean 17 as easily as it means 7) Actually, I hope you can get a new pet of some sort, so good luck.
