shift length/breaks questions

my coworker asked if I’d pick up her closing and i said yea sure even though i’m working the opening that day. it’s labor day so it’s time and a half. i start college that wednesday and my hours are gonna be cut because of my classes. i figured a 16 hour time and a half shift would help me get some money together before i start school.

even though i did this i literally hate work and its so exhausting to me, so i was just wondering how will my breaks total up in a shift of this length?

will i get one lunch and a bunch of 10’s or 2 half hour breaks. ive never worked a shift of more then 9 hours so i’m unsure lol.
