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?
First find how many packages the second center processes per day: 10000 packages/day * 3 = 
<gadget id="calculator">10000*3</gadget>
<output>30_000</output>
30000 packages/day.
Then add the packages the first center processes: 30000 packages/day + 10000 packages/day = 
<gadget id="calculator">30000+10000</gadget>
<output>40_000</output>
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 = $
<gadget id="calculator">2000*7</gadget>
<output>14_000</output>
14000/week.
