Leticia, Scarlett, and Percy decide to eat at a Greek restaurant for lunch. The prices for their dishes cost $10, $13, and $17, respectively. If the trio gives the waiter a 10% tip, how much gratuity should the waiter receive in dollars?

The total bill comes to $10 + $13 + $17 = $

<<10+13+17=40>>40. The total gratuity earned comes to $40 * 0.1 = $<<40*0.1=4>>4 #### 4 On national lipstick day, half of the students who attended class wore colored lipstick. Of those students who wore lipstick, one quarter wore red lipstick. There were one-fifth as many students wearing blue lipstick as were wearing red lipstick. If 200 students attended school that day, how many wore blue lipstick? Of 200 students who attended class, half wore colored lipstick, or 200/2=<<200/2=100>>100 students wore colored lipstick. Of those students who wore lipstick, one quarter wore red lipstick, or 100/4=<<100/4=25>>25 students wore red lipstick. Since there were one-fifth as many students wearing blue lipstick as were wearing red lipstick, then 25/5=<<25/5=5>>5 students wore blue lipstick. #### 5 Kendra wants enough shirts that she only has to do laundry once every two weeks. She wears one shirt to school for each of the five weekdays. Three days a week, she changes into a different shirt for an after-school club. On Saturday, she wears one shirt all day. On Sunday, she wears a different shirt to church than she does for the rest of the day. How many shirts does she need to be able to only do laundry once every two weeks? Kendra wears 1 * 5 = <<1*5=5>>5 shirts for school days. She wears 1 * 3 = <<1*3=3>>3 extra shirts for her after-school club. She wears 1 + 1 = <<1+1=2>>2 shirts on Sunday. With her shirt on Saturday, she wears 5 + 3 + 1 + 2 = <<5+3+1+2=11>>11 shirts each week. She wants to have 2 weeks’ worth of shirts, so she needs 11 * 2 = <<11*2=22>>22 shirts. #### 22 A TV show costs $100,000 per episode for the first season and twice that much for every other season. The first season had 12 episodes, and every season after that had 50% more episodes except the last season, which had 24 episodes. The show had 5 seasons. How much did it cost to produce all the episodes? The first season cost 12*100,000=$<<12*100000=1200000>>1,200,000 Season 2-4 had 12*.5=<<12*.5=6>>6 more episodes per season than the first So they each had 12+6=<<12+6=18>>18 episodes That means there were 18*3+24=<<18*3+24=78>>78 episodes in the last 4 seasons So those episodes cost 2*100,000=$<<2*100000=200000>>200,000 For a total cost of 200,000*78=$<<200000*78=15600000>>15,600,000 So the total cost was 15,600,000+1,200,000=$<<15600000+1200000=16800000>>16,800,000 #### 16,800,000 After violating the group's policies, 20 members of a Facebook group were removed by the group's admin. If each member posted 50 messages per day in the group and the number of members in the group was 150 before the admin removed some, calculate the total number of messages the remaining members would send in a week. If there were 150 members in the group before the admin removed 20, then 150-20 = <<150-20=130>>130 members remained after 20 were removed. The group members each posted 50 messages in a day, a total of 50*130 = <<50*130=6500>>6500 messages. In a week, with seven days, the group members would have posted 6500*7 = <<6500*7=45500>>45500 messages #### 45500 John buys 2 shirts. The first shirt costs $6 more than the second shirt. If the first shirt costs $15, how much, in dollars, did the shirts cost in total? The second shirt is 15-6=<<15-6=9>>9 dollars. Both shirts cost 15+9=<<15+9=24>>24 dollars. #### 24 Paul made two bank transfers of $90 and $60 respectively. A service charge of 2% was added to each transaction. If the second transaction was reversed (without the service charge), what is his account balance now if it was $400 before he made any of the transfers? 2% of $90 is (2/100)*$90 = $<<(2/100)*90=1.8>>1.8 2% of $60 is (2/100)*$60 = $<<(2/100)*60=1.2>>1.2 The second transaction was reversed without the service charge so only a total of $90+$1.8+$1.2 = $<<90+1.8+1.2=93>>93 was deducted from his account He will have a balance of $400-$93 = $<<400-93=307>>307 #### 307 A company has a tank that is already filled at a maximum capacity of 350,000 gallons of water. One day the tank starts losing 32,000 gallons/hour for 5 hours, after that time the company repaired the tank but it wasn't enough because the tank was still losing 10,000 gallons/hour. It stayed like that for 10 hours. In the second attempt, they managed to repair the tank and started filling it with 40,000 gallons/hour. After 3 hours, how many gallons are missing for the tank to be at maximum capacity again? In the first 5 hours the tank losses 32000 gallons/hour x 5 hours = <<32000*5=160000>>160000 gallons In the next 10 hours the tank losses 10,000 gallons/hour x 10 hours = <<10000*10=100000>>100000 gallons The total amount of water loss so far is 100000+160000 = <<100000+160000=260000>>260000 gallons The total amount of water remaining in the tank is 350000-260000 = <<350000-260000=90000>>90000 gallons. Once repaired, after 3 hours, the tank gains 40000 gallons/hour x 3 hours = <<40000*3=120000>>120000 gallons The total amount of water in the tank after the tank is filled for 3 hours is 120000+90000 = <<120000+90000=210000>>210000 gallons. The amount of water missing in the tank for it to be full is 350000-210000 = <<350000-210000=140000>>140000 gallons #### 140000 Tom eats a pound of carrots and twice as much broccoli. If carrots have 51 calories per pound and broccoli has 1/3 that many calories, how many calories did he eat in total? He ate 2 * 1 = <<2*1=2>>2 pounds of broccoli There are 51 / 3 = <<51/3=17>>17 calories in each pound of broccoli So he ate 2 * 17 = <<2*17=34>>34 calories of broccoli He ate 1 * 51 = <<1*51=51>>51 calories of carrots So in total he ate 51 + 34 = <<51+34=85>>85 calories #### 85 Jenna is making a costume for her role in Oliver Twist. She needs to make an overskirt and two petticoats. Each skirt uses a rectangle of material that measures 12 feet by 4 feet. She also needs to make a bodice that uses 2 square feet of material for the shirt and 5 square feet of fabric for each of the sleeves. If the material she uses costs $3 per square foot, how much does she spend on the material in total? First find the amount of material needed for one skirt: 12 feet * 4 feet = <<12*4=48>>48 square feet Then multiply that number by the number of skirts to find the total material used on the skirts: 48 square feet/skirt * 3 skirts = 144 square feet Then find the total amount of material she uses for the sleeves: 5 square feet/sleeve * 2 sleeves = <<5*2=10>>10 square feet Then add the amount of material she uses for each part of the dress to find the total amount of material: 10 square feet + 144 square feet + 2 square feet = <<10+144+2=156>>156 square feet Then multiply the total amount of material by the cost per square foot to find the total cost: 156 square feet * $3/square foot = $<<156*3=468>>468 #### 468
