Jennifer purchased 40 cans of milk at the store before meeting her classmate Mark, who was also buying milk. Jennifer bought 6 additional cans for every 5 cans Mark bought. If Mark purchased 50 cans, how many cans of milk did Jennifer bring home from the store?

If Mark bought 50 cans of milk, the number of times Jennifer added 6 cans for every 5 that Mark bought is 50/5 =

<<50/5=10>>10 times. The total number of additional cans she bought is 10*6 = <<10*6=60>>60 cans. If she initially had 40 cans, she went home with 40+60 = <<40+60=100>>100 cans of milk. #### 100 Sam and Jeff had a skipping competition at recess. The competition was split into four rounds. Sam completed 1 more skip than Jeff in the first round. Jeff skipped 3 fewer times than Sam in the second round. Jeff skipped 4 more times than Sam in the third round. Jeff got tired and only completed half the number of skips as Sam in the last round. If Sam skipped 16 times in each round, what is the average number of skips per round completed by Jeff? In round one, Jeff completed 16 - 1 = <<16-1=15>>15. In round two, Jeff completed 16 - 3 = <<16-3=13>>13. In round three, Jeff completed 16 + 4 = <<16+4=20>>20. In round four, Jeff completed 16 / 2 = <<16/2=8>>8. Jeff completed 15 + 13 + 20 + 8 = <<15+13+20+8=56>>56 skips in total. Jeff skipped an average of 56 / 4 = <<56/4=14>>14 skips per round. #### 14 Irene earns $500 if she works for 40 hours a week and gets an extra $20 for every hour of overtime. If she worked 50 hours last week, calculate her total income. If Irene worked 50 hours last week, the total number of hours counting as overtime is 50-40 = <<50-40=10>>10 hours. Since she's given $20 for every hour of overtime, she earned 10*$20 = $<<10*20=200>>200 in overtime. Her total income, including the overtime, is $500+$200= $<<500+200=700>>700 #### 700 Paityn has 20 red hats and 24 blue hats. Her friend Zola has 4/5 times as many red hats as she has and twice the number of blue hats. If they combine all the hats together and share them equally between themselves, calculate the number of hats each gets. Paityn has a total of 20 hats + 24 hats = <<20+24=44>>44 hats. The number of red hats that Zola has is 4/5 * 20 hats = <<4/5*20=16>>16 hats Zola also has 2 * 24 hats = <<2*24=48>>48 blue hats. Zola has a total of 48 hats + 16 hats = <<48+16=64>>64 hats. When they combine their hats, they have 64 hats + 44 hats = <<64+44=108>>108 hats If they share the hats equally, each get 108 hats / 2 people = <<108/2=54>>54 hats/person #### 54 Hans booked a room in a hotel. The hotel has 10 floors with 10 identical rooms on each floor. Because of an accident, the last floor is unavailable for the guests. Considering there are no other guests, in how many different rooms could Hans be checked in? The hotel has in total 10 floors * 10 rooms/floor = <<10*10=100>>100 rooms. One floor is unavailable, so Hans could be checked into 100 rooms - 10 rooms = <<100-10=90>>90 available rooms. #### 90 Four classmates were comparing their ages based on their birth month. They found out that Jolyn is 2 months older than Therese while Therese is 5 months older than Aivo. Then, Leon is 2 months older than Aivo. How much older in months is Jolyn than Leon? Jolyn is 2 + 5 = <<2+5=7>>7 months older than Aivo. Since Leon is 2 months older than Aivo, then Jolyn is 7 - 2 = 5 months older than Leon. #### 5 Peter goes to the store to buy a soda. The soda costs $.25 an ounce. He brought $2 with him and leaves with $.50. How many ounces of soda did he buy? He spend $1.5 on soda because 2 - .5 = <<2-.5=1.5>>1.5 He bought 6 ounces of soda because 1.5 / .25 = <<6=6>>6 #### 6 John's cow weighs 400 pounds. It increased its weight to 1.5 times its starting weight. He is able to sell the cow for $3 per pound. How much more is it worth after gaining the weight? The cow initially weighs 400*1.5=<<400*1.5=600>>600 pounds So it gained 600 - 400 = <<600-400=200>>200 pounds So its value increased by 200*$3 = $<<200*3=600>>600 #### 600 Brandon sold 86 geckos last year. He sold twice that many the year before. How many geckos has Brandon sold in the last two years? Last year: 86 geckos 2 years ago: 86(2)=172 Total number of geckos sold 86+172=<<86+172=258>>258 geckos #### 258 Krystian works in the library. He borrows an average of 40 books every day. Every Friday, his number of borrowed books is about 40% higher than the daily average. How many books does he borrow in a week if the library is open from Monday to Friday? The number of books borrowed on Friday is higher by 40 * 40/100 = <<40*40/100=16>>16 books. There are 5 days from Monday to Friday inclusive, so Krystian borrows an average of 5 * 40 = <<5*40=200>>200 books during that time. With Friday's increase in borrowings, during one week Krystian borrows 200 + 16 = <<200+16=216>>216 books. #### 216
