Question: Gary manages two Amazon distribution centers. The first center processes 10000 packages per day, and the second center processes three times that volume. If Amazon makes 5 cents of profit per package, how much profit per week do the two centers make combined?
Answer:
First find how many packages the second center processes per day: 10000 packages / day * 3 = 30000 packages / day. Then add the packages the first center processes: 30000 packages / day + 10000 packages / day = 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 = $14000 / week. The answer is 14000.
