Results summary component Flexbox

I'm not sure about 2 things in my code, any feedback about these are welcome.

NOTE: I didn't use any figma files, i've only use the given assets.

1. How about breakpoints? I've only set one for mobile, what are the others options available to fit the desired design?
2. How about the width of the 2 sections components? I'm pretty sure that my summary section is quite a bit to big regardless the final design, also my button seems strange, any advice for it is appreciated.
