Anthony has 16 pets. This morning he forgot to lock the door and he lost 6 pets. After that 1/5 of his pets died from old age. How many pets does he have left?

How many pets does he have left? ** Anthony lost 6 pets, so he has 16 - 6 =

<<16-6=10>>10 pets left. How many pets died from old age? ** Then 1/5 * 10 = <<1/5*10=2>>2 died from old age. How many pets does he have left? ** So, Anthony now has 10 - 2 = <<10-2=8>>8 pets. #### 8 In a spelling contest held in her school, Drew got 20 questions correct, winning her the competition. She got six questions wrong, and her compe***** Carla got 14 questions correct, and twice as many questions wrong as the number of questions Drew got wrong. If each compe***** was asked a different question, how many questions were asked in the competition? How many questions were asked of Drew? ** Since Drew got 20 questions right and 6 wrong, she was asked 20+6 = <<20+6=26>>26 questions. How many questions did Carla get wrong? ** Carla got twice as many questions wrong as Drew got, a total of 2*6 = <<2*6=12>>12 questions wrong. How many questions were asked of Carla? ** The total number of questions that Carla was asked is 12+14 = <<12+14=26>>26. How many questions were asked in the competition? ** Altogether, there were 26+26 = <<26+26=52>>52 questions that were asked in the contest. #### 52 Horatio is a poet composing sonnets for his lady fair. He believes it will take many of his sonnets to win her over. Each sonnet is fourteen lines long. His lady fair tells him to leave her alone after he reads her only seven sonnets, and Horatio is heartbroken over the 70 romantic lines he wrote that she never heard. How many sonnets did Horatio write in all? How many sonnets did Horatio never get to read? ** Horatio never got to read 70 / 14 = <<70/14=5>>5 sonnets. How many sonnets did Horatio write in all? ** He read his lady 7 sonnets, so he wrote 7 + 5 = <<7+5=12>>12 sonnets in all. #### 12 If 100 pieces, each 15 centimeters long, are cut from a 51-meter long ribbon, how much ribbon remains ? How many centimeters are cut from the ribbon? ** The total length cut from the 51-meter ribbon is 100 x 15 centimeters = <<100*15=1500>>1500 centimeters. How many meters are cut from the ribbon? ** Since 1 meter is equal to 100 centimeters, then 1500 centimeters is equal to 1500/100 = <<1500/100=15>>15 meters. How many meters of ribbon remain? ** Therefore, 51 - 15 = <<51-15=36>>36 meters of ribbon remains. #### 36 A church has 100 members who've volunteered to bake cookies for the homeless in their local town. If each member baked 10 sheets of cookies, and each sheet has 16 cookies, calculate the total number of cookies the church members baked? How many cookies did each church member bake? ** A sheet has 16 cookies, so if each church member baked 10 sheets, they each baked 10 sheets/person * 16 cookies/sheet = <<10*16=160>>160 cookies/person How many cookies did the church members bake in total? ** The total number of church members who decided to volunteer is 100, so in total, they baked 160 cookies/person * 100 people = <<100*160=16000>>16000 cookies #### 16000 Milly's babysitter charges $16/hour. Milly is considering switching to a new babysitter who charges $12/hour, but also charges an extra $3 for each time the kids scream at her. If Milly usually hires the babysitter for 6 hours, and her kids usually scream twice per babysitting gig, how much less will the new babysitter cost? How much does the first babysitter cost? ** First figure out how much the first babysitter costs by multiplying her hourly rate by the number of hours she works: $16/hour * 6 hours = $<<16*6=96>>96 How much does the second babysitter charge? ** Then use the same method to figure out how much the second babysitter charges before any screaming: $12/hour * 6 hours = $<<12*6=72>>72 How much does the second babysitter charge for two screams? ** Then figure out how much the babysitter charges for two screams: 2 screams * $3/scream = $<<2*3=6>>6 How much less will the new babysitter cost? ** Finally, subtract the second babysitter's two charges from the first babysitter's total charge to find the difference: $96 - $72 - $6 = $<<96-72-6=18>>18 #### 18 The cost of transporting 80 bags of cement, each weighing 50 kgs, is $6000. What's the cost of transporting three times as many cement bags, each weighing 3/5 times as many kgs? How many cement bags are there? ** Three times as many cement bags is 3*80 = <<3*80=240>>240 cement bags. How much does a bag of cement weigh? ** If a bag of cement weighs 50 kg, 3/5 times as much weight is 3/5*50 = <<3/5*50=30>>30 kgs. How much does it cost to transport one bag of cement? ** If the cost of transporting 80 bags of cement, each weighing 50 kgs, is $6000, the cost of transporting one bag of cement weighing 50 kg is $6000/80 = $<<6000/80=75>>75 How much does a bag weighing 30 kgs cost to transport? ** Since a bag weighing 50 kgs costs $75 to transport, a bag weighing 30 kgs will cost 30* $75/50 = $<<30*75/50=45>>45 to transport. How much does it cost to transport 240 bags of cement? ** The cost of transporting 240 cement bags each weighing 30 kgs is $45*240 = $<<45*240=10800>>10800 #### 10800 Mark has two dozen eggs to split with his three siblings. How many eggs does each person get to eat if they all eat the same amount? How many eggs are there? ** There are 24 eggs because 2 x 12 = <<2*12=24>>24 How many eaters are there? ** There are four eaters because 1 + 3 = <<1+3=4>>4 How many eggs do each person get to eat? ** They get 6 eggs each because 24 / 4 = <<24/4=6>>6 #### 6 Jason's dog has a tail that's half the length of its body, and a head that's 1/6 the length of its body. If the dog is 30 inches long overall, how long is its tail? How many inches are in the dog's body? ** If b is the length of the body, h is the length of the head, and t is the length of the tail, we know that b + h + t = 30, h = b/6 and t = b/2. We can substitute the second two equations into the first equation to get b + b/6 + b/2 = 30 How many inches are in the dog's body? ** Now multiply both sides of this equation by 6: 6b + b + 3b = 180 How many inches are in the dog's body? ** Now combine like terms: 10b = 180 How many inches are in the dog's body? ** Now divide both sides by 10: b = 180. How long is the dog's tail? ** The dog's body is 18 inches long. Now divide that length by 2 to find the length of its tail: 18 inches / 2 = <<18/2=9>>9 inches #### 9 A computer factory produces 1500 computers per day. They sell each computer for $150. If they sold 1 week's worth of production, how much money will the company earn? How many days are in one week? ** One week has 7 days. How many computers are produced in one week? ** The number of computers produced in 1 week is 1500 * 7 = <<1500*7=10500>>10500 computers. How much money will the company earn? ** The total amount earned selling 1 week of production is 10500 * 150 = $<<10500*150=1575000>>1575000. #### 1,575,000
