Experimenting with Insta Ads!

Good afternoon everyone!

I run a small comic strip on Instagram called "Kukuru", and I am considering utilizing the "insta ads" feature to advertise a few of the strips I've already posted.

I have a budget of about ~80$, will the ads be worth it?

If so, how should I go about it? what should I set for the number of days?

My goal is to grow to 10k followers before the end of the year, will doing this make this more viable?
