Three blue chips are in a jar which is 10% of the entire chips. If 50% of the chips are white and the rest are green, how many green chips are there?
10% + 50% = 60% of the chips in the jar are not green.
So, 100% - 60% = 40% of the chips are green.
There are 40%/10% = 4 sets of 10% to make 40%.
Hence, there are 3 chips x 4 sets =
<<3*4=12>>12 green chips. #### 12 One hundred people attended a party. Fifty percent of the attendees are women, thirty-five percent of them are men, and the rest are children. How many children attended the party? Out of 100 attendees, 100 x 50/100 = <<100*50/100=50>>50 are women. While 100 x 35/100 = <<100*35/100=35>>35 are men. So there were a total of 50 + 35 = <<50+35=85>>85 men and women who attended the party. Thus, 100 - 85 = <<100-85=15>>15 children attended the party. #### 15 Patty decides that to convince her brother and sister to do her chores in exchange for cookies. Patty agrees to give them 3 cookies for every chore they do. Each kid normally has 4 chores to do per week. Patty has $15 to buy cookies. Each pack of cookies contains 24 cookies and costs $3. How many weeks can Patty go without doing chores by paying her siblings with cookies? Patty can buy 5 packs of cookies because 15 / 3 = <<15/3=5>>5 Patty gets 120 cookies because 5 x 24 = <<5*24=120>>120 Patty would need to pay 12 cookies per week because 3 x 4 = <<3*4=12>>12 Patty can avoid 10 weeks of chores because 120 / 12 = <<120/12=10>>10 #### 10 Sherman has a 30-minute commute to the office and a 30-minute commute home every day. On the weekends, he spends 2 hours, each day, driving his kids to their different activities. How many hours does Sherman drive a week? He drives 30 minutes to work and 30 minutes home every day for a total of 30+30 = <<30+30=60>>60 minutes He makes this drive 5 days a week for a total of 5*60 = <<5*60=300>>300 minutes There are 60 minutes in 1 hour and he drives 300 minutes, 5 days a week so that's 300/60 = <<300/60=5>>5 hours He drives 2 hours on both Saturday and Sunday so he drives 2*2 = <<2*2=4>>4 hours on the weekends He commutes 5 hours during the week and spends 4 hours driving on the weekend for a total of 5+4 = <<5+4=9>>9 hours #### 9 William left Missouri by 7:00 AM and arrived at his hometown by 8:00 PM. He had 3 stops of 25, 10 and 25 minutes respectively during the journey. How many hours did he spend on the road? 8:00 PM is equivalent to 20:00 hrs so he spent a total of 20-7 = <<20-7=13>>13 hours on the journey He spent 25+10+25 = <<25+10+25=60>>60 minutes on stops There are 60 minutes in an hour so he spent (60/60) = <<60/60=1>>1 hour on stops Therefore, he spent 13-1 = <<13-1=12>>12 hours on the road. #### 12 James buys 6 t-shirts for 50% off. They each cost $20. How much did he pay? Each shirt cost 20*.5=$<<20*.5=10>>10 with the sale So he paid 10*6=$<<10*6=60>>60 #### 60 A museum has eight different wings displaying four times as many artifacts as paintings displayed. Three of the wings are dedicated to paintings. The artifacts are divided evenly among the remaining wings. One painting is so large it takes up an entire wing, and the other two wings house 12 smaller paintings each. How many artifacts are in each artifact wing? The museum has 2 * 12 + 1 = <<2*12+1=25>>25 paintings displayed in the painting wings. There are 4 times as many artifacts displayed, so there are 25 * 4 = <<25*4=100>>100 artifacts. There are 8 wings and 3 are painting wings, so there are 8 - 3 = <<8-3=5>>5 artifact wings. Each artifact wing has 100 / 5 = <<100/5=20>>20 artifacts in it. #### 20 Justin needs to collect one flower for each classmate that is in his 2nd-grade class. It takes him on average 10 minutes to find a flower he likes. He has been gathering for 2 hours. Assuming he has lost 3 of the flowers he initially gathered, how many more minutes does he need to look if he has 30 classmates? If he gathers for 2 hours, the number of minutes gathering is 2 * 60 minutes per hour = <<2*60=120>>120 minutes of gathering flowers Gathering for 120 minutes / 10 minutes per flower = <<120/10=12>>12 flowers gathered If he gathers 12 flowers initially but lost 3, he has 12-3 = <<12-3=9>>9 flowers gathered and kept Since he has 30 classmates total and has 9 flowers, he needs to gather 30-9=<<30-9=21>>21 more flowers Assuming it takes 10 minutes per flower, it will take him 10 * 21 = <<10*21=210>>210 minutes to gather the remaining 21 flowers needed #### 210 A citrus grove has laid out their plans for their sixteen orchards for the growing season. Lemons, their most popular citrus fruit, will take up eight orchards. Oranges are their second most popular fruit and will occupy half as many orchards as the lemons. Limes and grapefruits will split the remaining orchards. How many citrus orchards will be growing grapefruits? Oranges will occupy 8 / 2 = <<8/2=4>>4 orchards. There will be 16 - 8 - 4 = <<16-8-4=4>>4 orchards remaining for limes and grapefruits. Thus, 4 / 2 = <<4/2=2>>2 orchards will be growing grapefruits. #### 2 Oliver had $9, then he saved $5 from his allowance and spent $4 on a frisbee and $3 on a puzzle. His friend gives him another $8 as it's his birthday. How much money does Oliver have left? The total amount of money saved is $9 + $5 = $<<9+5=14>>14. The total cost of the frisbee and the puzzle is $4 + $3 = $<<4+3=7>>7. So Oliver has $14 - $7 = $<<14-7=7>>7 left. His friend gives him $8, so now he has $7 + $8 = $<<7+8=15>>15. #### 15
