Mr. John jogs for 1 hour 30 minutes in the morning every day. How much time (in hours) will he have spent jogging after two weeks?

There are 60 minutes in an hour so 1 hour 30 minutes is equivalent to [1 + (30/60)] hours =

<<1.5=1.5>>1.5 hours There are 7 days in a week so he spends 1.5*7 = <<7*1.5=10.5>>10.5 hours jogging every week After 2 weeks he will have spent 2*10.5 = <<2*10.5=21>>21 hours jogging. #### 21 Mark loves to see shows in theaters. He decided to visit the theater at least once a week. One performance lasts 3 hours. The price of the ticket depends on the time spent in the theater and stands at $5 for each hour. How much will Mark spend on visits to the theater in 6 weeks? The price of one performance is 3 * $5 = $<<3*5=15>>15. Mark intends to go to the theater once a week, so in 9 weeks he will spend 6 * $15 = $<<6*15=90>>90. #### 90 An unusual bicycle has 20 spokes on the front wheel and twice as many spokes on the back wheel. How many spokes does the bicycle have? The back wheel has double the spokes the front wheel has, which means the back wheel has 20*2=<<20*2=40>>40 spokes. In total, the bicycle has 20+40=<<20+40=60>>60 spokes. #### 60 For a project, a builder purchased 7 boxes of bolts with each box containing 11 bolts. He purchased 3 boxes of nuts with each box containing 15 nuts. He ended up finishing the project 6 days early and with 3 bolts and 6 nuts left over. How many bolts and nuts did he use for the project? The builder purchased 7 boxes * 11 bolts = <<7*11=77>>77 bolts. He used 77 bolts - 3 left over = <<77-3=74>>74 bolts for the project. The builder purchased 3 boxes * 15 nuts = <<3*15=45>>45 nuts. He used 45 nuts - 6 left over = <<45-6=39>>39 nuts for the project. Total for the project he used 74 bolts + 39 nuts = <<74+39=113>>113 nuts and bolts. #### 113 Two vampires have come to the sleepy village of Willowton, population 300. Every night, each vampire turns 5 more people into vampires. How many vampires are there after two nights? First find the number of new vampires after one night: 5 people/vampire * 2 vampires = <<5*2=10>>10 people Add that to the starting number of vampires to find the total number of vampires after one night: 10 vampires + 2 vampires = <<10+2=12>>12 vampires Then find the number of new vampires on the second night: 5 people/vampire * 12 vampires = <<5*12=60>>60 people Add that number to the starting number of vampires on the second night to find the total number of vampires after two nights: 60 vampires + 12 vampires = <<60+12=72>>72 vampires #### 72 Bobby needs to buy a new pair of fancy shoes. He decides to go to a cobbler and get them handmade. The cobbler charges $250 to make the mold. He then charges $75 an hour for 8 hours to make the shoes. The cobbler agrees to only charge 80% of the cost for work to make the shoes, since it is his first pair of shoes. How much did Bobby pay? The cost of labor is 75*8=$<<75*8=600>>600 So Bobby pays 600*.8=$<<600*.8=480>>480 So that means Bobby pays 480+250=$<<480+250=730>>730 #### 730 Jack went to a supermarket with $100 and bought 4 bottles of water. Then his mother called him and asked him to buy twice as many bottles as he already bought. Each bottle cost $2. Finally, he also bought half a pound of cheese and 1 pound of cheese costs $10. How much money does Jack have remaining? Jack's mother asked him to buy 2 * 4 = <<2*4=8>>8 bottles of water. Thus Jack bought 4 + 8 = <<4+8=12>>12 bottles of water in total. Altogether, the bottles of water cost 12 * $2 = $<<12*2=24>>24. The cheese cost 1/2 * $10 = $<<10*0.5=5>>5. So Jack spent $24 + $5 = $<<24+5=29>>29 on water and cheese. Since he started with $100, he now has $100 - $29 = $<<100-29=71>>71 left. #### 71 Kyle is 5 years older than Julian. Julian is 20 years younger than Frederick. Frederick is 2 times older than Tyson. If Tyson is 20, how old is Kyle? Frederick is 20 * 2 = <<20*2=40>>40 years old Julian is 40 - 20 = <<40-20=20>>20 years old Kyle is 20 + 5 = <<20+5=25>>25 years old #### 25 Teddy has 7 dogs and 8 cats. Ben has 9 more dogs than Teddy, and Dave has 13 more cats and 5 less dogs than Teddy. How many pets do all of them have combined? Teddy has 7+8 = <<7+8=15>>15 pets in total. Ben has 9+7 = <<9+7=16>>16 dogs, which means he has 16 pets in total. Dave has 13+8 = <<13+8=21>>21 cats. Dave has 7-5 = <<7-5=2>>2 dogs. Dave has 21+2 = <<21+2=23>>23 pets in total. Combined, they have 15+16+23 = <<15+16+23=54>>54 pets in total. #### 54 Carrie wants to buy a new iPhone. The new iPhone costs $800. She can trade in her Samsung Galaxy for $240. She can make $80 per week babysitting. How many weeks does she have to work before she can purchase the iPhone? The total cost of the iPhone will cost Carrie $800 - $240 = $<<800-240=560>>560. It will take her $560 / $80 = <<560/80=7>>7 weeks to earn enough money. #### 7
