Emir wants to buy a dictionary that costs $5, a dinosaur book that costs $11, and a children's cookbook that costs $5. He has saved $19 from his allowance. How much more money does Emir need to buy all three books?

The total cost of the dictionary, the dinosaur book, and the cookbook is $5 + $11 + $5 = $

<<5+11+5=21>>21. Emir needs $21 − $19 = $2. #### 2 James made $4000 in January. The next month he made twice as much. In March, however, James made $2000 less than in February. How much has James made so far this year? In February James made 4000 * 2 = <<4000*2=8000>>8000. In March James made 8000-2000 = <<8000-2000=6000>>6000. In total for the year James has made 4000 + 8000 + 6000 = $<<4000+8000+6000=18000>>18000. #### 18000 Marissa is serving her kids lunch. Each kid gets a burger with 400 calories and 5 carrot sticks with 20 calories each, and some cookies with 50 calories each. Marissa wants each kid to eat a total of 750 calories for lunch. How many cookies does each kid get? First figure out how many total calories come from the carrots by multiplying the calories per carrot by the number of carrots: 20 calories/carrot * 5 carrots = <<20*5=100>>100 calories Then subtract the calories the kids have already eaten from the goal number of calories to find out how many more total calories they should eat: 750 calories - 400 calories - 100 calories = <<750-400-100=250>>250 calories Then divide the total number of calories by the calories per cookie to find the number of cookies each kid gets: 250 calories / 50 calories/cookie = <<250/50=5>>5 cookies #### 5 Anna has 3 times as many toys as Mandy and 2 fewer toys than Amanda. If they have 142 toys all together, how many toys does Mandy have? Let x be the number of toys Mandy has. Anna has 3*x toys. Amanda has 3*x+2 toys. x+3*x+3*x+2=142 7*x+2=142 7*x=140 x=<<20=20>>20 #### 20 Andrew bought 750 stickers. He shared some of his stickers with his friends, Daniel and Fred. Daniel received 250 stickers, while Fred received 120 more stickers than Daniel. He kept the remaining stickers. How many stickers did Andrew keep? Fred received 250 + 120 = <<250+120=370>>370 stickers. Thus, Andrew shared 250 + 370 = <<250+370=620>>620 stickers. Therefore, Andrew kept 750 - 620 = <<750-620=130>>130 stickers. #### 130 John adopts a dog from a shelter. The dog ends up having health problems and this requires 3 vet appointments, which cost $400 each. After the first appointment, John paid $100 for pet insurance that covers 80% of the subsequent visits. How much did he pay in total? He got a discount of 400*.8=$<<400*.8=320>>320 He got that discount for 3-1=<<3-1=2>>2 visits So each of those visits cost 400-320=$<<400-320=80>>80 So he paid 2*80=$<<2*80=160>>160 for those visits That means he paid a total of 400+160+100=$<<400+160+100=660>>660 #### 660 Jessica’s class is going to a farm for a field trip. The school will bring all 35 students in the class plus 4 adult chaperones. The farm entrance fee for students costs $5 and $6 for adults. How much will the school pay for the farm entrance in all? The students' entrance fee cost $5 x 35 = $<<5*35=175>>175. The adults' entrance fee cost $6 x 4 = $<<6*4=24>>24. Therefore, the school will pay a total of $175 + $24 = $<<175+24=199>>199 for the farm entrance. #### 199 John's dog has a litter of 8 puppies. He gives away half of them. He keeps one of the remaining puppies. He then takes the remaining puppies and sells them each for $600. He had to give the owner of the stud $300. How much money does he profit? He had 8/2=<<8/2=4>>4 left after giving some puppies away He then keeps one so he sells 4-1=<<4-1=3>>3 puppies That means he made 3*600=$<<3*600=1800>>1800 So his profit was 1800-300=$<<1800-300=1500>>1500 #### 1500 Anna puts three slices of ham in each sandwich. If she has 31 slices of ham, how many more slices of ham does she need to make 50 ham sandwiches? Anna needs 3 x 50 = <<3*50=150>>150 slices of ham to make 50 sandwiches. Anna needs 150 - 31 = <<150-31=119>>119 more slices of ham #### 119 Nancy and Rose are making bracelets, and there are eight beads in each bracelet. Nancy has 40 metal beads and 20 more pearl beads. Rose has 20 crystal beads and twice as many stone beads as crystal beads. How many bracelets can Nancy and Rose make? Nancy has 40 + 20 = <<40+20=60>>60 pearl beads. So, Nancy has a total of 40 + 60 = <<40+60=100>>100 beads. Rose has 2 x 20 = <<2*20=40>>40 stone beads. So, Rose has 20 + 40 = <<20+40=60>>60 beads. Thus, Nancy and Rose have 100 + 60 = <<100+60=160>>160 beads altogether. Therefore, they can make 160/8 = <<160/8=20>>20 bracelets. #### 20
