First find how many packages the second center processes per day: 10000 packages/day * 3 = <<10000*3=30000>>30000 packages/day
Then add the packages the first center processes: 30000 packages/day + 10000 packages/day = <<30000+10000=40000>>40000 packages/day
Then multiply the number of packages by Amazon's profit per package to find Amazon's daily profit: 40000 packages/day * $0.05/package = $2000/day
Then multiply the daily profits by the number of days in a week to find the weekly profits: $2000/day * 7 days/week = $<<2000*7=14000>>14000/week
#### 14000
