1. The foowing is an equivalence relation on {g, e, r, m, a, n, y} : {(g, g),(g, m), (g, n), (m, g), (m, m), (m, n), (n, g), (n, m),(n, n), (e, e), (r, r), (r, a),(a, r), (a, a),(y, y)}.
What is the partition that this relation induces?

Ataxi company charges $2.25 for the first mile and then $0.20 per mile for each additional mile, or f = $2.25 + $0.20(m - 1) where f is the fare and m is the number of miles. if juan's taxi fare was $6.05, how many miles did he travel in the taxi? if juan's taxi fare was 7.65, how many miles did he travel in taxi
