Heisenberg owns a pharmacy. He earned a total of $80 from 100 mg amoxicillin and $60 from 500 mg amoxicillin every week. If each capsule of 100 mg amoxicillin costs $5 and each capsule of 500 mg amoxicillin costs $2, how many capsules of amoxicillin does he sell every 2 weeks?

Heisenberg sells a total of $80/5=

<<80/5=16>>16 capsules of 100 mg amoxicillin every week. So, the total number of 100 mg amoxicillin he sells every 2 weeks is 16 x 2= <<16*2=32>>32. And he sells $60/2= <<60/2=30>>30 capsules of 500 mg amoxicillin every week. So, the total number of 500 mg amoxicillin he sells every 2 weeks is 30 x 2= 60. Therefore, the total number of capsules he sells every 2 weeks is 60 + 32 = <<60+32=92>>92. #### 92 Kelly needs school supplies to teach her class for an art project. She has 8 students and they will need 3 pieces of construction paper each. In addition to the construction paper, she needs to buy 6 bottles of glue for everyone to share. After Kelly purchases these supplies, she dropped half of them down a storm drain. Class is about to start, but she manages to rush to the store and buy 5 more pieces of construction paper. How many supplies are left? Kelly needs 8*3=<<8*3=24>>24 pieces of construction paper. She buys glue which grows the supplies to 24+6=<<24+6=30>>30. Unfortunately, she dropped 30/2=<<30/2=15>>15 supplies. Rushing to the store, she buys more construction paper bringing her supplies back to 15+5=<<15+5=20>>20. #### 20 Bret takes a 9 hour train ride to go to Boston. He spends 2 hours reading a book, 1 hour to eat his dinner, and 3 hours watching movies on his computer. How many hours does he have left to take a nap? For all his activities on the train, Bret spends 2 + 1 + 3 = <<2+1+3=6>>6 hours. For his nap, he has 9 - 6 = <<9-6=3>>3 hours left. #### 3 Carrie harvested 200 tomatoes and 350 carrots on her farm. If she can sell a tomato for $1 and a carrot for $1.50, how much money can she make if she sells all of her tomatoes and carrots? From selling her tomatoes, she can make 200 * $1 = $<<200*1=200>>200. From selling her carrots, she can make 350 * $1.50 = $<<350*1.5=525>>525. The total amount of money she can make is $200 + $525 = $<<200+525=725>>725. #### 725 6 kids in Carolyn's daycare prefer peas, 9 prefer carrots, and 5 prefer corn. What percentage of the children prefer corn? First find the total number of children: 6 kids + 9 kids + 5 kids = <<6+9+5=20>>20 kids Then divide the number of kids who prefer corn by the total number of kids and multiply by 100% to express as a percentage: 5 kids / 20 kids * 100% = 25% #### 25 Jim has 2 rows of 4 trees to start. When he turns 10 he decides to plant a new row of trees every year on his birthday. On his 15th birthday after he doubles the number of trees he has. How many trees does he have? He started with 2*4=<<2*4=8>>8 trees He plants trees for 15-10=<<15-10=5>>5 years So he planted 5*4=<<5*4=20>>20 trees So he had 20+8=<<20+8=28>>28 trees After doubling them he had 28*2=<<28*2=56>>56 trees #### 56 Johnny is out walking his two dogs at night, and his son joins him for the walk. How many legs' worth of organisms are traveling together for this walk? As Johnny and his son are humans, and humans walk on two legs, this means that between the two of them there are 2*2=<<2*2=4>>4 legs' worth of organisms. There are two dogs walking along as well, and since dogs walk on 4 legs this means there are 2*4=<<2*4=8>>8 legs' worth of organisms. We add these two totals together to find there are 4+8=<<4+8=12>>12 legs' worth of organisms in total. #### 12 Carson is refilling his tires. Each tire can hold 500 cubic inches of air. Two of the tires are completely flat and empty. One tire is 40% full and the last tire is 70% full. If Carson injects 50 cubic inches of air with each pump, how many pumps will it take him to fill all the tires? First, if the a full tire needs 500 cubic inches of air, then two empty tires need: 500 cubic inches/tire * 2 tires = <<500*2=1000>>1000 cubic inches. Accordingly, the 40%-full tire needs 500 cubic inches * (100%-40%). So, we find the 40%-full tire needs 500 cubic inches * (60%) = <<500*(60*.01)=300>>300 cubic inches. And, the 70%-full tire needs 500 cubic inches * (100%-70%). So, the 70%-full tire needs 500 cubic inches * (30%)= <<500*(30*.01)=150>>150 cubic inches. Now add up the needs of all the tires to find the total number of cubic inches needed: 1000 cubic inches + 300 cubic inches + 150 cubic inches = <<1000+300+150=1450>>1450 cubic inches. Finally, if the pumps each hold 50 cubic inches, the total number of pumps needed is 1550 cubic inches / 50 cubic inches/pump = 29 pumps. #### 29 Joel is picking peppers from his garden. He picks 7 on Sunday, 12 on Monday, 14 on Tuesday, 12 on Wednesday, 5 on Thursday, 18 on Friday and 12 on Saturday. He knows that in his garden 20% of the peppers are hot and the rest are not. How many non-hot peppers did he pick? He picked 80 peppers because 7 + 12 + 14 + 12 + 5 + 18 + 12 = <<7+12+14+12+5+18+12=80>>80 80% of the peppers are not hot because 100 - 20 = <<100-20=80>>80 He picked 64 non-hot peppers because 80 x .8 = <<80*.8=64>>64 #### 64 Teresa orders 2 fancy ham and cheese sandwiches for $7.75 each at a local shop. While there, she decides to pick up some salami for $4.00, more brie which is three times the price of the salami, a 1/4 pound of olives that are $10.00 per pound, 1/2 pound of feta cheese that’s $8.00 a pound and another loaf of french bread that is $2.00. How much does she spend at the local shop? She orders 2 sandwiches that are $7.75 so they cost 2*$7.75 = $<<2*7.75=15.50>>15.50 The brie is three times more expensive than the $4.00 salami so the brie costs 3*$4 = $<<3*4=12.00>>12.00 She buys 1/4 pound of the olives that costs $10.00 a pound so they cost .25*$10 =$<<1/4*10=2.50>>2.50 She buys 1/2 pound of feta that costs $8.00 a pound so it costs .5*$8 = $<<1/2*8=4.00>>4.00 The salami is $4.00, the brie is $12.00, olives are $2.50 and the feta is $4.00 and the sandwiches are $15.50 for a total of $4+$12+$2.50+$4+$15.50 = $<<4+12+2.5+4+15.50=38.00>>38.00 Adding the french bread gives $38.00+$2.00 = $<<38+2=40>>40 #### 40
