Hannah slips on a banana peel and breaks her arm. The doctor charges her $200 for the cast, $300/hour for a 30-minute visit, $4/pill for 30 painkillers, and $6/hour for a mandatory minimum of 2 hours of parking. How much does the doctor's visit cost total?
First find the length of the visit in hours: 30 minutes / 60 minutes/hour = 
<gadget id="calculator">30/60</gadget>
<output>1/2 = around 0.5</output>
.5 hours.
Then find the total cost of the visit: $300/hour * .5 hours = $
<gadget id="calculator">300*.5</gadget>
<output>150</output>
150.
Then find the total cost of the painkillers: $4/pill * 30 pills = $
<gadget id="calculator">4*30</gadget>
<output>120</output>
120.
Then find the cost of the parking: $6/hour * 2 hours = $
<gadget id="calculator">6*2</gadget>
<output>12</output>
12.
Then add all the different costs to find the total cost: $12 + $120 + $150 + $200 = $
<gadget id="calculator">12+120+150+200</gadget>
<output>482</output>
482.
