Allison, a YouTuber, uploads 10 one-hour videos of food reviews each day to her channel. She uploaded videos halfway through June,  at that pace,  and then doubled the number of video hours she uploaded on the remaining days. What's the total number of video hours she has uploaded at the end of the month?
Since June has 30 days, halfway is 1/2*30 = <<1/2*30=15>>15
The total number of video hours halfway through June is 10*15 = <<10*15=150>>150
When she doubled the number of video hours, the total per day became 10*2 = <<10*2=20>>20
The total number of video hours for the remaining days is 15*20 = <<15*20=300>>300
The total number of video hours for the whole month is 300+150 = <<300+150=450>>450
