One-fourth of the airing time of a television program is spent on commercials. If there are 6 thirty-minute programs, how many minutes are spent on commercials for the whole duration of the 6 programs?

The total time of the programs is 6 programs * 30 minutes/program =

<<6*30=180>>180 minutes A quarter of this time is spent on commercials, so that's 180 minutes / 4 = <<180/4=45>>45 minutes #### 45 Last Sunday, Logan went to church and realized that the number of children present was 80. If there were 60 male adults, and the total number of people in the church was 200, how many female adults were present? The total number of male adults and children is 80+60 = <<80+60=140>>140 people. The number of females is 200-140 = <<200-140=60>>60 female adults. #### 60 Mark has kangaroos and goats. Kangaroos have two legs and goats have four legs. If he has 23 kangaroos and three times as many goats as kangaroos what is the total number of legs of all his animals? His kangaroos have a total of 23*2=<<23*2=46>>46 legs He has 23*3=<<23*3=69>>69 goats The goats have 69*4=<<69*4=276>>276 legs So in total his animals have 276+46=<<276+46=322>>322 legs #### 322 Lisa is a member of the photography club at school. Every weekend the club will go anywhere to take photos. Leslie took 10 photos of animals to share with the club. She also took 3 times as many photos of flowers as animals and took 10 fewer scenery than the flowers. If Lisa took 15 fewer photos last weekend, How many photos did she take then? Lisa took 10 x 3 = <<10*3=30>>30 photos of flowers. She took 30 - 10 = <<30-10=20>>20 photos of the scenery. So, Lisa took 10 + 30 + 20 = <<10+30+20=60>>60 photos this week. Therefore, Lisa took 60 - 15 = <<60-15=45>>45 photos last weekend. #### 45 A local business was selling 25 raffle tickets to raise money for charity. Each ticket cost $2.00 apiece. They sold all the tickets and also received 2 $15 donations and a $20 donation. How much money did they raise? They sold 25 raffle tickets at $2.00 a piece so 25*2 = $<<25*2=50.00>>50.00 They received 2 $15.00 donations so 2*15 = $<<2*15=30>>30 With another donation of $20, in total, they raised 50+30+20 = $<<50+30+20=100.00>>100.00 #### 100 Josh buys 3 packs of string cheese. Each piece of string cheese cost 10 cents. Each pack has 20 string cheeses in them. How many dollars did he pay? Each pack cost 20*10=<<20*10=200>>200 cents So each pack cost 200/100=$<<200/100=2>>2 That means he pays 2*3=$<<2*3=6>>6 #### 6 A ship left a port and headed due west, having 400 pounds of food for the journey's supply. After one day of sailing, 2/5 of the supplies had been used by the sailors in the ship. After another two days of sailing, the sailors used 3/5 of the remaining supplies. Calculate the number of supplies remaining in the ship to last the sailors until they dock. After one day of sailing, 2/5*400 = <<2/5*400=160>>160 pounds of food supplies had been used. The total number of supplies remaining in the ship is 400-160 = <<400-160=240>>240 pounds. After another 2 days of sailing, 3/5*240 = <<3/5*240=144>>144 pounds of food had been used. The total number of supplies remaining in the ship is now 240-144 = <<240-144=96>>96 pounds. #### 96 In the garden, the gecko eats 12 bugs. The lizard eats half as many bugs as the gecko. The frog eats 3 times as many bugs as the lizard. The toad eats 50% more bugs than the frog. How many bugs are eaten in total by all of them? Lizard eats 12 / 2 = <<12/2=6>>6 bugs. Frog eats 6 x 3 = <<6*3=18>>18 bugs. Toad eats 18 x 1.50 = <<18*1.50=27>>27 bugs. The lizard, frog and toad eat 6 + 18 + 27 = <<6+18+27=51>>51 bugs. Adding what the gecko eats, a total of 12 + 51 = <<12+51=63>>63 bugs are eaten. #### 63 Kim plants 80 cherry pits. 25% of them sprout and Kim sells 6 of the saplings. How many cherry saplings does she have left? First find the number of saplings that sprout: 80 pits * 25% = <<80*25*.01=20>>20 saplings Then subtract the number she sold to find the number she has left: 20 saplings - 6 saplings = <<20-6=14>>14 saplings #### 14 John eats 10 potato chips that have a total of 60 calories. He then eats 6 cheezits that each have 1/3 more calories than a chip. How many total calories did he eat? The chips each have 60/10 = <<60/10=6>>6 calories That means the cheezits have 6/3 = <<6/3=2>>2 calories more than each chip So they have 6 + 2 = <<6+2=8>>8 calories each That means they have 6 * 8 = <<6*8=48>>48 total calories So in total, he ate 60 + 48 = <<60+48=108>>108 calories #### 108
