How do you say hi in French

Ineed french . i am writing sentences i wrote in english in french. could someone check to see if the french translations are correct in regards to linguistics such as grammar? 1. i like the bookstore the best. > > > j’aime la librairie le meilleur. 2. i don’t spend a lot. maybe 30$ dollars. > > > je ne dépenser pas beaucoup. peut-être trente dollars. 3. the jewelry store is the most expensive. > > > la bijouterie est le plus cher. 4. i pay with money. > > > je payer avec l’argent.

In this french correct ? i dont know if the person i am talking to is a female or male im assuming that wouldn't affect it but i kind of forget . i know all adjectives agree with the nouns that they modify. métier is masculine so i use the adjective bon and bon is masculine so i use un? is that how it works je pense un bon métier pour toi est un artiste ou un architecte. i think a good job for you is an artist or an architect

Translate this to french: hi xavier! how are you doing? i have been taking math and english classes lately. they are both in the afternoon. today i went to dance, and it was fun. till next time!
