Responsive Pricing component with toggle jQuery

I tried to use only CSS with this, even tried to handle it with selectors as :checked, :focus and even multiple classes but it didn't solve it 100%, also I even gave Sass a try but figured out this is still JS so I will just use JS -_-

But I really liked it, guess I like handling prices.

Also if anyone knows a better way to figure out the designs dimensions, that would be great, As I won't waste time with a pixel perfect in this matter.
