Kiaan is doing home delivery of newspapers in his neighborhood of 200 homes. After an hour of work, he has distributed newspapers to 2/5 of the homes. After another 2 hours of working, he realizes he has distributed newspapers to 60 percent of the remaining homes. How many homes does he still need to distribute the newspapers to?

After the first hour of work, he has distributed newspapers to 2/5*200 =

<<2/5*200=80>>80 homes The number of homes that still need newspapers is 200-80 = <<200-80=120>>120 Two hours later, the number of homes he has distributed newspapers to is 60/100 * 120 = <<60/100*120=72>>72 homes. The number of homes he still needs to distribute newspapers to is 120-72 = <<120-72=48>>48 homes #### 48 Paul is collecting license plates from different states. He has plates from 40 different states. For each percentage point of total US states that he has, his parents will give him $2. How much does he earn from them? The proportion of plates that he has out of total states is .8 because 40 / 50 = <<40/50=.8>>.8 He has 80% of the plates because .8 x 100 = <<.8*100=80>>80 He makes $160 because 80 x 2 = <<80*2=160>>160 #### 160 Martha gets prize points every time she shops at her local grocery store. She gets 50 points per $10 spent, plus a 250 point bonus if she spends more than $100. Martha buys 3 pounds of beef for $11 each, 8 pounds of fruits and vegetables for $4/pound, 3 jars of spices for $6 each, and other groceries totaling $37. How many points does Martha get? First find the total cost of the beef: $11/pound * 3 pounds = $<<11*3=33>>33 Then find the total cost of the fruits and vegetables: $4/pound * 8 pounds = $<<4*8=32>>32 Then find the total cost of the spices: $6/jar * 3 jars = $<<6*3=18>>18 Now add the cost of all the items to find Martha's total spending: $33 + $32 + $18 + $37 = $<<33+32+18+37=120>>120 Now divide 50 points by $10 to find now many points Martha gets per dollar: 50 points / $10 = <<50/10=5>>5 points/dollar Now multiply this exchange rate by Martha's total spending to find how many points she gets before the bonus: $120 * 5 points/dollar = <<120*5=600>>600 points Finally, add the 250 point bonus Martha gets for spending more than $100: 600 points + 250 points = 850 points #### 850 Roxy has 7 flowering plants in her garden. She has twice as many fruiting plants as her flowering plants. On Saturday, she goes to the nursery and buys 3 flowering plants and 2 fruiting plants. On Sunday, she gives away 1 flowering plant and 4 fruiting plants to her neighbor, Ronny. How many plants are remaining in her garden? Roxy’s flowering plant count is <<7=7>>7. Her fruiting plant count is 7 x 2 = <<7*2=14>>14. On Saturday, her flowering plant count is 7 + 3 = <<7+3=10>>10. On Saturday, her fruiting plant count is 14 + 2 = <<14+2=16>>16. On Sunday, her flowering plant count is 10 - 1 = <<10-1=9>>9. On Sunday, her fruiting plant count is 16 - 4 = <<16-4=12>>12. Roxy’s remaining plant count in her garden is 9 + 12 = <<9+12=21>>21. #### 21 Sean designs and sells patches. He orders his patches in a unit of 100 and is charged $1.25 per patch. If he turns around and sells all 100 patches for $12.00 each, what is his net profit? He orders 100 patches and they cost $1.25 each so the patches are 100*1.25 = $<<100*1.25=125.00>>125.00 He sells each of the 100 patches for $12.00 each so he makes 100*12 = $<<100*12=1200.00>>1,200.00 He makes $1,200.00 selling patches and spends $125.00 to have them made so his net profit is 1200-125 = $<<1200-125=1075.00>>1,075.00 #### 1075 Era had 5 burgers for her and her 4 friends. She sliced each burger into halves. The first and second friends got 1 and 2 slices, respectively. Then the third and fourth friends got 3 slices each. How many slices of burgers are left for Era? There are 5 x 1/2 = 10 halves of burgers made from 5 whole burgers. Era's first and second friends got 1 + 2 = <<1+2=3>>3 slices together. Her third and fourth friends got 3 + 3 = <<3+3=6>>6 slices together. Era's four friends got 3 + 6 = <<3+6=9>>9 slices. So, Era is left with 10 - 9 = <<10-9=1>>1 slice. #### 1 Mark is reading books, for 2 hours each day. He decided to increase his time spent on reading books weekly, by 4 hours. How much time does Mark want to spend during one week on reading books? Currently, Mark is reading books for 2 * 7 = <<2*7=14>>14 hours weekly.

To find the number of total bike rides, we must first determine how many times John rode his bike. We do this by performing 17*2= <<17*2=34>>34 times for John Since John's mother rode 10 times more than John did, we find her total by performing 34+10=<<34+10=44>>44 times For all three people put together then, we perform 44+34+17=<<44+34+17=95>>95 times in total #### 95 Lisa was collecting socks to donate to a homeless shelter. She bought 12 pairs at a discount store. Sandra, her friend, came over and brought her 20 pairs of socks. Her cousin showed up with one-fifth the number of pairs that Sandra bought. After work, Lisa’s mom brought 8 more than three times the number of pairs Lisa started with. How many pairs of socks did Lisa end up with? Her cousin brought over 20/5=<<20/5=4>>4 pairs of socks Three times more than Lisa bought was 12*3=<<12*3=36>>36 Her mom brought 36+8=<<36+8=44>>44 pairs of socks In total Lisa had 12+20+4+44=<<12+20+4+44=80>>80 pairs of socks #### 80 20% of the vets in a state recommend Puppy Kibble. 30% recommend Yummy Dog Kibble. If there are 1000 vets in the state, how many more recommend Yummy Dog Kibble than Puppy Kibble? The number of vets that recommend Puppy Kibble is 1000*.2=<<1000*.2=200>>200. The number of vets that recommend Yummy Dog Kibble is 1000*.3=<<1000*.3=300>>300 vets. Thus, 300-200=<<300-200=100>>100 more vets recommend Yummy Dog Kibble than Puppy Kibble. #### 100
