Brendan makes $6/hour as a waiter. He's scheduled for 2 8-hour shifts and 1 12-hour shift this week. He also makes an average of $12 in tips each hour. Brendan is supposed to pay 20% of his income in taxes, but he only reports 1/3rd of his tips to the IRS. How much money does Brendan pay in taxes each week?
First find the total number of hours Brendan works for the 8-hour shifts: 2 shifts * 8 hours/shift = 
<gadget id="calculator">2*8</gadget>
<output>16</output>
16 hours.
Then find the total number of hours Brendan works by adding those hours to the 12-hour shift: 16 hours + 12 hours = 
<gadget id="calculator">16+12</gadget>
<output>28</output>
28 hours.
Now find Brendan's total wage earnings by multiplying his $6/hour wage by the number of hours he works: $6/hour * 28 hours = $
<gadget id="calculator">6*28</gadget>
<output>168</output>
168/week.
Now figure out how much Brendan makes in tips by multiplying the number of hours he works by the amount of tips he makes per hour: $12/hour * 28 hours/week = $
<gadget id="calculator">12*28</gadget>
<output>336</output>
336/week.
Now divide that number by 3, since Brendan only reports a third of his tips: $336/week / 3 = $
<gadget id="calculator">336/3</gadget>
<output>112</output>
112/week.
Now add Brendan's wage earnings to that number to find how much income he reports to the IRS each week: $168/week + $112/week = $
<gadget id="calculator">168+112</gadget>
<output>280</output>
280/week.
Finally, multiply Brendan's reported income by his tax rate to find how much he pays in taxes each week: $280/week * .2 = $
<gadget id="calculator">280*.2</gadget>
<output>56</output>
56/week.
