One set of barrettes costs $3 each, and one comb costs $1 each. Kristine buys one set of barrettes and one comb. Crystal buys three sets of barrettes and one comb. How much do the two girls spend altogether?

Kristine spends $3 + $1 = $

<<3+1=4>>4. Three sets of barrettes cost 3 x $3 = $<<3*3=9>>9. Crystal spends $9 + $1 = $<<9+1=10>>10. Therefore, the two girls spend $4 + $10 = $<<4+10=14>>14. #### 14 In the first team, Beth scored 12 while Jan scored 10. In the second team, Judy scored 8 while Angel scored 11. How many more points did the first team get than the second team? Beth and Jan scored a total of 12 + 10 = <<12+10=22>>22. Judy and Angel scored a total of 8 + 11 = <<8+11=19>>19. Thus, the first team scores 22 - 19 = <<22-19=3>>3 more points than the second team. #### 3 Kalani has twenty candles in her bedroom, twice the number of candles in the living room. Donovan, her brother, brings in 20 more candles he bought from the candle shop. What's the total number of candles in the house? If the number of candles in the bedroom is twice the number in the living room, there are 20/2 = <<20/2=10>>10 candles in the living room. When Donovan brings in 20 more candles, the total number of candles becomes 10+20+20 = <<10+20+20=50>>50 #### 50 At the Taylor family reunion, there were 45 kids and 123 adults. When they sat down to eat, there were 14 tables. How many people sat at each table? There were 45 kids + 123 adults = <<45+123=168>>168 people at the reunion. All the people sat at 14 tables, so 168 people / 14 tables = <<168/14=12>>12 people per table. #### 12 Axel bought an aquarium that was marked down 50% from an original price of $120. But he also paid additional sales tax equal to 5% of the reduced price. What was the total cost of the aquarium? The aquarium was bought for $120 x 50/100 = $<<120*50/100=60>>60 less. So the marked down price of the aquarium was $120 - $60 = $<<120-60=60>>60. Axel paid $60 x 5/100 = $<<60*5/100=3>>3 additional for the sales tax. Therefore, the total cost of the aquarium was $60 + $3 = $<<60+3=63>>63. #### 63 Alannah, Beatrix, and Queen are preparing for the new school year and have been given books by their parents. Alannah has 20 more books than Beatrix. Queen has 1/5 times more books than Alannah. If Beatrix has 30 books, how many books do the three have together? If Beatrix has 30 books, Alannah has 30 books + 20 books = <<30+20=50>>50 books. Queen has 1/5 * 50 books = <<1/5*50=10>>10 more books than Alannah. The total number of books Queen has is 50 books + 10 books = <<50+10=60>>60 books. All three have 60 books + 50 books + 30 books = <<60+50+30=140>>140 books together #### 140 Maiya has two sisters. The first sister is twice as old as Maiya. The first sister is 1 year younger than Maiya. Their average age is 5. How old is Maiya? Their total age is 15 because 3 x 5 = <<3*5=15>>15 15 - X - 2X -(X-1) is equivalent to 16 = 4X Maiya is 4 years old because 16 / 4 = <<16/4=4>>4 #### 4 Toby, the Alaskan Malamute, can pull a sled at a speed of 20 miles per hour if the sled is unloaded, but he pulls the same sled at a speed of 10 miles per hour if the sled is fully loaded. If Toby takes a continuous 4-part journey, first pulling the loaded sled for 180 miles, then pulling the unloaded sled for 120 miles, then pulling the loaded sled 80 miles, and finally, pulling the unloaded sled another 140 miles, how many hours in total will Toby spend pulling the sled? Pulling a loaded sled at 10 mph for 180 miles takes 180/10=<<180/10=18>>18 hours Pulling an unloaded sled at 20 mph for 120 miles takes 120/20=<<120/20=6>>6 hours Pulling a loaded sled at 10 mph for 80 miles takes 80/10=<<80/10=8>>8 hours Pulling an unloaded sled at 20 mph for 140 miles takes 140/20=<<140/20=7>>7 hours In total, Toby will have pulled the sled for 18+6+8+7=<<18+6+8+7=39>>39 hours #### 39 Ben bought a lawnmower for his garden. He paid $100 for it. After six months, the value of the mower dropped by about 25%. Over the next year, the value of the mower dropped another 20% in value. How much is Ben's lawnmower worth after this time? The first value drop of the lawnmower was 25/100 * 100 = $<<25/100*100=25>>25. So the lawnmower was worth 100 - 25 = $<<100-25=75>>75. Over the next year, the value dropped another 20%, which is 20/100 * 75 = $<<20/100*75=15>>15. So after all this time, Ben's lawnmower is worth 75 - 15 = $<<75-15=60>>60. #### 60 Roger had a 6-hour drive planned out. He didn't want to listen to music so he downloaded several podcasts. The first podcast was 45 minutes long. The second podcast was twice as long as that. The third podcast was 1 hour and 45 minutes long. His fourth podcast is 1 hour long. How many hours will his next podcast have to be to fill up the full 6 hours? The second podcast was twice as long as the first so 2*45 = <<2*45=90>>90 1 hour is 60 mins. So his 1 hour and 45 min podcast is 60+45 = <<1*60+45=105>>105 minutes long So far he has downloaded 45+90+105+60 = <<45+90+105+60=300>>300 min If he converts 300 min to hours then he has 300/60 = <<300/60=5>>5 hours of podcasts downloaded He has 5 hours of podcasts and his drive is 6 hours so he will need 6 - 5 = <<6-5=1>>1 more hour of podcasts #### 1
