Tom decides to give his wife an anniversary getaway.  The plane tickets cost $5000 each.  The hotel is 20% more expensive than normal because it is a busy weekend.  The normal price is $1500 per day.  If they are there for 3 days how much did the trip cost?
The hotel room is 1500*.2=$
<gadget id="calculator">1500*.2</gadget>
<output>300</output>
300 more expensive per night than normal.
So they paid 1500+300=$
<gadget id="calculator">1500+300</gadget>
<output>1_800</output>
1800 per night.
That means she paid 1800*3=$
<gadget id="calculator">1800*3</gadget>
<output>5_400</output>
5400.
The plane tickets cost 5000*2=$
<gadget id="calculator">5000*2</gadget>
<output>10_000</output>
10,000.
So the total cost is 10,000+5400=$
<gadget id="calculator">10000+5400</gadget>
<output>15_400</output>
15,400.
