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 = $

<<50+10=60>>60/person Then multiply that cost by the number of people to find the total cost of entrees and tickets: $60/person * 6 people = $<<60*6=360>>360 Now find how many people ordered drink tickets: 6 people / 2 = <<6/2=3>>3 people Now find the total cost of the drink tickets: 3 people * $30/person = $<<3*30=90>>90 Now find the total cost of the evening: $90 + $360 = $<<90+360=450>>450 Now multiply this quantity by 90% to find the amount of the refund: $450 * .9 = $<<450*.9=405>>405 Now subtract the refund amount from the total cost to find how much money the friends lost: $450 - $405 = $<<450-405=45>>45 #### 45 There were 15 males and 10 more girls at the party. Each attendee received 2 cans of soft drinks. If Mary bought several boxes of soft drinks where a box contains 8 cans and is priced at $5 for each box, how much did Mary spend on soft drinks? There were 10 + 15 = <<10+15=25>>25 girls in the party. So, there were a total of 15 + 25 = <<15+25=40>>40 attendees. 40 x 2 = <<40*2=80>>80 cans of soft drinks are needed. So, Mary bought 80/8 = <<80/8=10>>10 boxes of soft drinks. Therefore, Mary spent 10 x $5 = $<<10*5=50>>50 on soft drinks. #### 50 Suzanne wants to raise money for charity by running a 5-kilometer race. Her parents have pledged to donate $10 for her first kilometer and double the donation for every successive kilometer. If Suzanne finishes the race, how much money will her parents donate? For the 2nd kilometer, the donation will be $10 * 2 = $<<10*2=20>>20. For the 3rd kilometer, the donation will be $20 * 2 = $<<20*2=40>>40. For the 4th kilometer, the donation will be $40 * 2 = $<<40*2=80>>80. For the final kilometer, the donation will be $80 * 2 = $<<80*2=160>>160. For the entire race the donation will be $10 + $20 + $40 + $80 + $160 = $<<10+20+40+80+160=310>>310. #### 310 Niles is collecting his book club's annual fees. Each of the six members pays $150/year towards snacks, plus $30 each for six hardcover books and $12 each for six paperback books. How much money does Niles collect in total? First find the cost per member of the hardcover books: $30/book * 6 books = $<<30*6=180>>180. Then find the cost per member of the paperback books: $12/book * 6 books = $<<12*6=72>>72. Then find the total cost per member: $180 + $72 + $150 = $<<180+72+150=402>>402/member. Now find the total amount of money by multiplying the cost per member by the number of members: $402/member * 6 members = $<<402*6=2412>>2412. #### 2412 The sky currently has 4 times as many cirrus clouds as cumulus clouds, and 12 times as many cumulus clouds as cumulonimbus clouds. If the sky currently has 3 cumulonimbus clouds, how many cirrus clouds are in the sky at this moment? The sky has 3*12=<<3*12=36>>36 cumulus clouds. The sky has 4*36=<<4*36=144>>144 cirrus clouds. #### 144 Every day, while going to school, Shane drives a total of 10 miles. Calculate the total distance he drives in an 80 day semester from home to school and back. To go to school and back, Shane drives 2*10 = <<2*10=20>>20 miles per day. In 80 days of a semester, he drives for 80*20 = <<80*20=1600>>1600 miles #### 1600 John buys a pair of earbuds that cost $200. If tax was 15%, how much did he pay after tax? The tax was 200*.15=$<<200*.15=30>>30 So he paid 200+30=$<<200+30=230>>230 #### 230 Missy has an obedient dog and a stubborn dog. She has to yell at the stubborn dog four times for every one time she yells at the obedient dog. If she yells at the obedient dog 12 times, how many times does she yell at both dogs combined? First find the number of times Missy yells at the stubborn dog: 4 * 12 times = <<4*12=48>>48 times Then add the number of times she yells at the obedient dog to find the total number of times she yells: 48 times + 12 times = <<48+12=60>>60 times #### 60 Jonas is trying to expand his wardrobe. He has 20 pairs of socks, 5 pairs of shoes, 10 pairs of pants and 10 t-shirts. How many pairs of socks does he need to buy to double the number of individual items in his wardrobe? First, we must recognize that all pairs of shoes and socks are actually two items each, whereas the pants and the t-shirts are individual items. Therefore there are 20*2= <<20*2=40>>40 individual socks in 20 pairs of socks. Similarly, there are 5*2=<<5*2=10>>10 individual shoes in 5 pairs of shoes. Therefore, Jonas has 40+10+10+10= <<40+10+10+10=70>>70 individual items in his collection. To double this number, we perform 70*2=<<70*2=140>>140. This means we need 140-70=<<140-70=70>>70 new items to double the size. Since there are 2 individual socks in each pair, we take 70/2= <<70/2=35>>35 new pairs of socks. #### 35 At a university there are 1800 students. 30% of all the students are from other countries. Starting next semester, 200 new foreign students will begin studying at this University. How many foreign students will then study at the University if all other students continue to study? In the beginning, there are 30/100 * 1800 students = <<30/100*1800=540>>540 foreign students. In the next semester, there are going to be 540 foreign students + 200 foreign students = <<540+200=740>>740 foreign students in total. #### 740
