Jenny signs up for dinner theater with 5 of her friends. Each person pays $50 for the ticket and $10 for their entrée, and half the people also buy unlimited drink tickets for $30/person. Then the dinner theater is canceled due to COVID, and each person gets a 90% refund. How much money did the group of six friends lose?
First find the cost of the ticket and the entrée for each person: $50/person + $10/person = $
<gadget id="calculator">50+10</gadget>
<output>60</output>
60/person.
Then multiply that cost by the number of people to find the total cost of entrees and tickets: $60/person * 6 people = $
<gadget id="calculator">60*6</gadget>
<output>360</output>
360.
Now find how many people ordered drink tickets: 6 people / 2 = 
<gadget id="calculator">6/2</gadget>
<output>3</output>
3 people.
Now find the total cost of the drink tickets: 3 people * $30/person = $
<gadget id="calculator">3*30</gadget>
<output>90</output>
90.
Now find the total cost of the evening: $90 + $360 = $
<gadget id="calculator">90+360</gadget>
<output>450</output>
450.
Now multiply this quantity by 90% to find the amount of the refund: $450 * .9 = $
<gadget id="calculator">450*.9</gadget>
<output>405</output>
405.
Now subtract the refund amount from the total cost to find how much money the friends lost: $450 - $405 = $
<gadget id="calculator">450-405</gadget>
<output>45</output>
45.
