Which form would be the correct form for the reflexive verb "se laver" for the subject "je"?

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.

Fill in the blank with the right form of the verb: non, il ne pas au père noël. (croire) fill in the blank with the right form of the verb: oui, je la (voir)

Iwant to make sure im right on this one, the 'manger' should be 'mange' in this sentence right? "je manger la pizza."
