Kevin is trying to reorganize his favorite apps on his phone. He has so many! Each page can have 5 rows of 4 apps. There is also space for 4 apps on the bottom of the screen that will not change and are the same for each page of apps. For the 4 fixed apps, Kevin has a phone icon, a camera icon, an internet browser icon, and the weather icon. Kevin has a total of 5 app pages. The last page has only 2 apps in addition to the 4 fixed apps on the bottom. Pages 1-3 are full. Page 4 still has space for 5 more apps. How many apps are on Kevin's phone?
