Haley is getting ready to watch a comet fly over her house. She spends two hours shopping for a telescope, half an hour getting everything set up in the backyard, three times the setup time making snacks, and 20 minutes watching the comet. What percentage of the total time she spent on all those activities was spent watching the comet, rounded to the nearest percent?

First convert Haley's shopping time to minutes: 2 hours * 60 minutes/hour =

<<2*60=120>>120 minutes Then convert Haley's setup time to minutes: .5 hours * 60 minutes/hour = <<.5*60=30>>30 minutes Then find the total time she spends making a snack: 3 * 30 minutes = <<3*30=90>>90 minutes Then add the time she spends on each activity to find the total time: 120 minutes + 30 minutes + 90 minutes = <<120+30+90=240>>240 minutes Then divide the time she spends watching the comet by the total time and multiply by 100% to express the answer as a percentage: 20 minutes / 240 minutes = 8.333...%, which rounds down to 8% #### 8 Will's breakfast supplied him 900 calories of energy. Then he decided to jog for half an hour, which used up 10 calories of energy per minute. What is Will's net calorie intake after jogging? Will jogged for 60/2 = <<60/2=30>>30 minutes. He was able to use up 10 x 30 = <<10*30=300>>300 calories for jogging. The net calorie intake of Will after jogging is 900 - 300 = <<900-300=600>>600. #### 600 Victory and Sam have saved money for their holiday spending. Victory saves $100 less than Sam. If Sam saves $1000, how much is the total money saved for holiday spending? Victory saves $1000 - $100 = $<<1000-100=900>>900 for holiday spending. The total money saved is $1000 + $900 = $<<1000+900=1900>>1900. #### 1900 In Dana's senior high school class there were 200 students. 60% of the students were female, and 50% of the females were brunettes. If 50% of the female brunettes were under 5 feet tall, then how many female brunettes in Dana's high school senior class were under 5 feet tall? In Dana's senior class, the 60% of 200 students is 0.6*200=<<0.6*200=120>>120 female students. Fifty percent of the females, or 0.5*120=<<0.5*120=60>>60 of the female students were brunettes. If 50% of the female brunettes were under 5 feet tall, then there were 60*0.5=<<50*.01*60=30>>30 female brunettes under five feet tall in Dana's senior class. #### 30 Cilia wants to buy a multi-level dumbbell system. The first pair of dumbbells are 3 lb weights, the second pair is 5 lb weights and the third is 8 lb pounds. How much does the entire system weigh? The first pair of weights weighs 3 lb each so all total they weigh 2*3 = <<3*2=6>>6 lbs The second pair of weights weigh 5 lbs each so they weigh 2*5 = <<5*2=10>>10 lbs The third pair of weights weigh 8 lbs each so they weigh 2*8 = <<8*2=16>>16lbs All total, the entire system of weights weigh 6+10+16 = <<6+10+16=32>>32 lbs #### 32 Adam has three more than twice as many tattoos as Jason has. If Jason has two tattoos on each of his arms and three tattoos on each of his legs, how many tattoos does Adam have? 2 tattoos on each arm is a total of 2*2=<<2*2=4>>4 tattoos. 3 tattoos on each leg is a total of 2*3=<<2*3=6>>6 tattoos. Thus, Jason has 4+6=<<4+6=10>>10 tattoos. Twice the number of tattoos that Jason has is 2*10=<<2*10=20>>20 tattoos. Adam has 3 more than twice the number Jason has, or 3+20=<<3+20=23>>23 tattoos. #### 23 Jane is shopping for some fruit. She sees a stand of fruit advertising 10 apples for $2, and another one advertising 5 oranges for $1.50. Assuming there's no price discount for buying in bulk, how much would Jane spend in cents if she bought 12 of the cheaper of the two fruits? First, we need to find out which fruit is cheaper individually. We start by figuring out the price for a single apple by performing 200/10= <<200/10=20>>20 cents per apple. Then we find out the price of an individual orange, by performing 150/5=<<150/5=30>>30 cents per orange. Since 20<30, the apples are cheaper. To determine the answer, we multiply 20*12= <<20*12=240>>240 cents #### 240 Marsha works as a delivery driver for Amazon. She has to drive 10 miles to deliver her first package, 28 miles to deliver her second package, and half that long to deliver her third package. If she gets paid $104 for the day, how many dollars does she get paid per mile? First find how far Marsha drives to deliver the third package: 28 miles / 2 = <<28/2=14>>14 miles Then find how many miles she drives total by adding the miles for the three legs of her journey: 14 miles + 28 miles + 10 miles = <<14+28+10=52>>52 miles Then divide her total pay by the number of miles she drives to find her pay per mile: $104 / 52 miles = $<<104/52=2>>2/mile #### 2 Samira is the assistant coach of a soccer team playing against one of the best teams in their league. She has four dozen water bottles filled with water in a box. In the first break of the match, the 11 players on the field each take two bottles of water from Samira's box, and at the end of the game, take one more bottle each. How many bottles of water are remaining in Samira's box? If the box has four dozen bottles of water, there are 4*12 = <<4*12=48>>48 bottles of water in the box After the first half, the 11 players take 11*2 = <<11*2=22>>22 bottles of water from the box. If they take 11 more bottles of water at the end of the game, the number increases to 22+11 = 33 bottles of water taken Without the bottles taken, there are 48-33 =<<48-33=15>>15 bottles of water remaining in the box #### 15 During one game, a total of 50 people attended a baseball team’s games. Forty percent and thirty-four percent of the audiences are supporters of the first and second teams, respectively. How many people attended the game did not support either of the teams? 50 x 60/100 = <<50*60/100=30>>30 people support the first team. 50 x 34/100 = <<50*34/100=17>>17 people support the second team. So, a total of 30 + 17 = <<30+17=47>>47 people supported the first and second teams. Thus, 50 - 47 = <<50-47=3>>3 people did not support either team. #### 3
