Jenna is buying concert tickets for her group of five friends. She's able to get two of the tickets from the concert website for $50 each before they sell out. A scalper offers to sell her two more tickets for 240% of the normal price, but Jenna convinces him to give her $10 off that total payment. Finally, one of her friends gets a discounted ticket through her job for 60% of the normal price. How much do Jenna's friends pay for their tickets in total?

First calculate the price of the two normally priced tickets by multiplying the price and the quantity: $50 * 2 = $

<<50*2=100>>100 Then calculate the scalper's initial asking price by multiplying the normal cost of two tickets by 240%: $100 * 2.4 = $<<100*2.4=240>>240 Then subtract the $10 discount Jenna negotiated: $240 - $10 = $<<240-10=230>>230 Now calculate the price of the discounted ticket Jenna's friend gets through her job by multiplying the normal ticket price by 60%: $50 * .6 = $<<50*.6=30>>30 Finally, add up the price of all the tickets to find the total: $100 + $230 + $30 = $<<100+230+30=360>>360 #### 360 Cheryl ate 7 m&m's after lunch. She ate 5 m&m's after dinner, and she gave some to her sister. If Cheryl had 25 m&m's at the beginning, how many did she give to her sister? Cheryl at 7 + 5 = <<7+5=12>>12 m&m's She gave 25 - 12 = <<25-12=13>>13 m&m's to her sister. #### 13 There are one-third as many Ford trucks as Dodge trucks in the parking lot of the Taco Castle. But there are twice as many Ford trucks as Toyota trucks in this parking lot, and there are half as many Volkswagen Bugs as there are Toyota trucks in this same parking lot. If there are 5 Volkswagon Bugs in the parking lot, how many Dodge trucks are in the parking lot of the Taco Castle? If there are half as many VW Bugs as there are Toyota trucks in this parking lot, and there are 5 VW Bugs, then there are 2*5=<<2*5=10>>10 Toyota trucks in the parking lot. And if there are twice as many Ford trucks as Toyota trucks in this parking lot, then there are 2*10=<<2*10=20>>20 Ford trucks in the parking lot. And if there are one-third as many Ford trucks as Dodge trucks in the parking lot, then there are 20*3=<<20*3=60>>60 Dodge trucks in the parking lot of the Taco Castle. #### 60 Jason bought a new bookcase that can hold a maximum of 80 pounds of weight. Jason has 70 hardcover books that each weigh half a pound, 30 textbooks that each weigh 2 pounds, and 3 knick-knacks that each weight 6 pounds. How many pounds over the bookcase's weight limit is this total collection of items? First find the total weight of the hardcover books: 70 books * .5 pound/book = <<70*.5=35>>35 pounds Then find the total weight of the textbooks: 30 books * 2 pounds/book = <<30*2=60>>60 pounds Then find the total weight of the knick-knacks: 3 knick-knacks * 6 pounds/knick-knack = <<3*6=18>>18 pounds Then find the total weight of all the items: 35 pounds + 60 pounds + 18 pounds = <<35+60+18=113>>113 pounds Then subtract the bookcase's weight limit: 113 pounds - 80 pounds = <<113-80=33>>33 pounds #### 33 James is building a hall of mirrors. Three of the walls will be completed covered with glass. If two of those walls are 30 feet by 12 feet and the third is 20 feet by 12 feet, how many square feet of glass does he need? First find the area of one of the long walls: 30 feet * 12 feet = <<30*12=360>>360 square feet Then double that amount since there are two walls: 360 square feet * 2 = <<360*2=720>>720 square feet Then find the area of the short wall: 20 feet * 12 feet = <<20*12=240>>240 square feet Then add that area to the area of the two long walls to find the total area: 720 square feet + 240 square feet = <<720+240=960>>960 square feet #### 960 Abigail spent 60% of her money on food, and 25% of the remainder on her phone bill. After spending $20 on entertainment, she is left with $40. How much money did Abigail have initially? Abigail had $20 + $40 = $<<20+40=60>>60 left after paying her phone bill. The $60 is 100% - 25% = 75% of the remainder of her money after spending for food. Since 75% is $60, then 1% is $60/75 = $<<60/75=0.80>>0.80. Thus, Abigail had $0.80 x 100 = $<<0.80*100=80>>80 left after she spent money on food. The $80 is 100% - 60% = 40% of her original money. So 1% is $80/40 = $<<80/40=2>>2. Therefore, Abigail initially had $2 x 100 = $<<2*100=200>>200. #### 200 Each class uses 200 sheets of paper per day. The school uses a total of 9000 sheets of paper every week. If there are 5 days of school days, how many classes are there in the school? Each class uses 200 x 5 = <<200*5=1000>>1000 sheets of paper in a week. Thus, there are 9000/1000 = <<9000/1000=9>>9 classes in the school. #### 9 Matt can make a batch of a dozen cookies using 2 pounds of flour. He uses 4 bags of flour each weighing 5 pounds. If Jim eats 15 cookies how many cookies are left? Matt used 4*5=<<4*5=20>>20 pounds of flour That means he made 20/2=<<20/2=10>>10 batches So he cooked 10*12=<<10*12=120>>120 cookies After Jim eats 15 there are 120-15=<<120-15=105>>105 cookies left #### 105 If the normal hours of operation of Jean's business are 4 pm to 10p every day Monday through Friday, and from 6 pm to 10 pm on weekends, how many hours is the business open in a week? First, we find the number of hours per weekday by subtracting the smaller number time from the larger one, finding 10-4= <<10-4=6>>6 hours per weekday. As there are 5 weekdays, this means the business is open 6*5=30 hours a week on the weekdays. Then we find out the amount of time the business is open on a weekend day, using the same process as we did with the weekdays, finding Jean's business is open 10-6= <<10-6=4>>4 hours each weekend day. Since there are two weekend days, this means they are open 4*2=<<4*2=8>>8 hours on the weekends. We add these two totals together to find that 30+8= <<30+8=38>>38 hours per week. #### 38 Kendall is counting her change. She has a total of $4 in quarters, dimes, and nickels. If she has 10 quarters and 12 dimes, how many nickels does she have? The total money from the quarters is 10 * $0.25 = $<<10*0.25=2.50>>2.50 The total money from the dimes is 12 * $0.10 = $<<12*0.10=1.20>>1.20 The total money from the nickels is $4 - $2.50 - $1.20 = $<<4-2.5-1.2=0.30>>0.30 The number of nickels Kendall has is $0.30 / $0.05 = <<0.30/0.05=6>>6 nickels #### 6
