I have two more job interviews tomorrow and they both seem very interested in me. If they both offer me a job how would I pick?

There is a school that I applied for which is a teacher’s assistant job. Is at a academy school and I have a virtual interview in two hours. On the phone earlier she told me about the school in a position in the pay and she asked me if it was something I was interested in. Of course I want to make sure I’m happy. It’s a 9 hour day job, five days a week. It pays $17.90 an hour. The other job interview is a preschool assistant and this one’s like an 8 hour job and it pays $13.00 an hour. This one’s a lot further for me but only like 14 minutes when I drive. School is only like 10 minutes away when I walk but it’s like a two minute drive. They’re both the same positions but different age groups. What is one offered me a job first, am I allowed to say I’ll think about it? I’m just I need a job.
