Best way to make 20$ a week?

I’m not looking to make a living nor do I expect to make anything close to one, I’m just looking for a way to make around 20$ a week. I’m 15 and have access to a computer and an iPhone. Slightly less than 20 would also be fine! I have lots of free time (I do school from my laptop) and I can handle tedious and time consuming tasks! Any recommendations would be much appreciated!
