How to make subscribe button on same line as input box in Mailchimp embed form

Right now, I have it so the subscribe button and the field for inputting email are on separate lines and the button size is small with awkward spacing in between the field and the button. I'd like to fix these issues by having the button and the input field for email on the same line. If you could just add/remove whatever needs to be done to this I would REALLY appreciate it:

My code for this Mailchimp embed form is like this right now:

<!-- Begin Mailchimp Signup Form -->
<link href="//cdn-images.mailchimp.com/embedcode/classic-10_7.css" rel="stylesheet" type="text/css">
<style type="text/css">

   #mc-embedded-subscribe { background-color: #930e0e !important; }
#mc-embedded-subscribe:hover { background-color:#ce3939 !important; }
