Bill decides to bring donuts to work for a meeting that day. He buys a box of donuts that has 50 in total in them. He eats 2 on the ride in because he's hungry. When he gets to the office, the secretary takes another 4 out of the box when he's not looking. Lastly, right before the meeting Bill sets the box down on his desk and leaves the office to take a phone call. While Bill's away, his coworkers steal half the remaining donuts. Bill comes back and brings the box into his meeting. How many donuts are left in the box?

Bill eats 2 donuts out of a box of 50 for 50-2=

<<50-2=48>>48 donuts remaining. The secretary takes 4 more donuts out of the box, leaving 44 donuts remaining. Bills coworkers take half of the remaining donuts, leaving 44/2= <<44/2=22>>22 donuts remaining. #### 22 Boris has 100 pieces of Halloween candy. His daughter eats 8 pieces of candy. He separates the remaining pieces of candy into equal portions into 4 different bowls. Then he takes away 3 pieces of candy from each bowl to keep for himself. How many pieces of candy are in one bowl? After his daughter eats some candy, Boris has 100 - 8 = <<100-8=92>>92 pieces of candy In one bowl, there are 92 / 4 = <<92/4=23>>23 pieces of candy After Boris takes some candy for himself, there are 23 - 3 = <<23-3=20>>20 pieces of candy in one bowl #### 20 One-half of a pound of mangoes costs $0.60. How many pounds can Kelly buy with $12? One pound of mangoes cost $0.60 x 2 = $<<0.60*2=1.20>>1.20. So Kelly can buy $12/$1.20 = <<12/1.20=10>>10 pounds of mangoes. #### 10 A Ferris wheel can accommodate 70 people in 20 minutes. If the Ferris wheel is open from 1:00 pm until 7:00 pm, how many people will get to ride? The Ferris wheel will be open for 7:00 - 1:00 = 6 hours. In one hour the wheel can ride 60 minutes / 20 minutes = <<60/20=3>>3 times the number of riders. The total per hour riders is 3 * 70 people = <<3*70=210>>210 people. If the ride is open 6 hours * 210 people = <<6*210=1260>>1260 people can ride. #### 1260 Yvonne and Janna were writing their 1000-word pair research paper. Yvonne was able to write 400 words while Janna wrote 150 more words than Yvonne. When they edited their paper, they removed 20 words and added twice as many words as they removed. How many more words should they add to reach the research paper requirement? Janna wrote 400 + 150 = <<400+150=550>>550 words. Together, they wrote 400 + 550 = <<400+550=950>>950 words. They have 950 - 20 = <<950-20=930>>930 words left after omitting 20 words. Then 20 x 2 = <<20*2=40>>40 words were added during the editing. Overall, they have 930 + 40 = <<930+40=970>>970 words. Thus, they should add 1000 - 970 = <<1000-970=30>>30 more words. #### 30 Andy works in the pro shop at a tennis resort, where he earns $9 an hour. In addition to this, he gets paid $15 for each racquet he restrings, $10 for changing out the grommets on a racquet, and $1 for painting a stencil on the racquet strings. How much does he earn (before taxes) during an 8-hour shift if he strings 7 racquets, changes 2 sets of grommets, and paints 5 stencils? Andy works 8 hours, so he earns a wage of 8 hours * $9 per hour = $<<8*9=72>>72 just for working there. During that time, he restrings 7 racquets, so he earns 7 racquets * $15 per racquet = $<<7*15=105>>105 from stringing. He also changed the grommets in 2 of those racquets, so he earned 2 grommet jobs * $10 per grommet job = $<<2*10=20>>20 from changing grommets. And he stenciled 5 racquets, so he earned 5 stencil jobs * $1 per stencil job = $<<5*1=5>>5 for stenciling. In total, Andy earned $72 + $105 + $20 + 5 = $<<72+105+20+5=202>>202 for the day. #### 202 Briar is attending a one-week community empowerment event and has to take a cab ride to the event and back home every day. A cab ride costs $2.5 per mile. If the event is 200 miles away from Briar's home, calculate the total amount of money the cab rides cost would be at the end of the event? If a cab ride costs $2.5 per mile, and Briar has to go to an event 200 miles away, he will spend 200* $2.5 = $<<200*2.5=500>>500 one way to the trip. Since the round trip is also 200 miles and Briar is charged $500, the total amount he spends in a day to go to the event and back is $500+$500 = $<<500+500=1000>>1000 The event is one week, meaning Briar will have to spend $1000*7 = $<<1000*7=7000>>7000 on the cab rides #### 7000 Because of the migration of salmon, the total number of salmon in river Trout has increased by ten times the number initially in the river. If there were 500 salmons initially, calculate the total number of fish in the river now. If the number of salmons in the river increased by ten times the number initially there, then 500*10 = <<500*10=5000>>5000 new salmons migrated up the river. The total number of salmon in the river now is 5000+500 = <<5000+500=5500>>5500 #### 5500 The maximum safe amount of caffeine you can consume per day is 500 mg. If each energy drink has 120 mg of caffeine and Brandy drinks 4 of them, how much more caffeine can she safely consume that day? First find the total amount of caffeine Brandy already drank: 120 mg/drink * 4 drinks = <<120*4=480>>480 mg Then subtract that amount from the amount it's safe to consume daily to find the remaining amount Brandy can consume: 500 mg - 480 mg = <<500-480=20>>20 mg #### 20 An artist spends 30 hours every week painting. If it takes her 3 hours to complete a painting, how many paintings can she make in four weeks? She completes 30 hours/week / 3 hours/painting = <<30/3=10>>10 paintings/week So in one month, she paints 10 paintings/week * 4 weeks/month = <<10*4=40>>40 paintings #### 40
