One ticket to the underground costs $3. In one minute, the metro sells an average of 5 such tickets. What will be the earnings from the tickets in 6 minutes?

During one minute the metro sells 5 tickets, so they earn 5 * 3 = $

<<5*3=15>>15. So in 6 minutes they would earn 15 * 6 = $<<15*6=90>>90. #### 90 Gretchen read that you should spend 10 minutes walking for every 90 minutes you spend sitting. If Gretchen spends 6 hours working at her desk, how long will she spend walking? First find the total number of minutes Gretchen spends sitting at her desk: 6 hours * 60 minutes/hour = <<6*60=360>>360 minutes Then divide this amount by 90 minutes to find how many walking breaks Gretchen takes: 360 minutes / 90 minutes/break = <<360/90=4>>4 breaks Then multiply the number of breaks by the length of each break to find how long Gretchen spends walking: 4 breaks * 10 minutes/break = <<4*10=40>>40 minutes #### 40 A portable battery charger can fully charge a smartphone in 26 minutes or a tablet in 53 minutes. Ana charged her tablet fully and her phone halfway. How many minutes did it take? Ana charged her phone halfway, so she took 26 / 2 = <<26/2=13>>13 minutes to charge her phone. Thus, it took Ana 13 + 53 = <<13+53=66>>66 minutes to charge her phone and tablet. #### 66 Ray always takes the same route when he walks his dog. First, he walks 4 blocks to the park. Then he walks 7 blocks to the high school. Finally, he walks 11 blocks to get back home. Ray walks his dog 3 times each day. How many blocks does Ray's dog walk each day? The number of blocks in each walk around the neighborhood is 4 blocks + 7 blocks + 11 blocks = <<4+7+11=22>>22. Ray's dog walks 3 walks × 22 blocks/walk = <<3*22=66>>66 blocks each day. #### 66 Jackie spends 8 hours working, 3 hours of exercise and spends 8 hours of sleep per day. How much free time does Jackie have? Jackie spends a total of 8 + 8 + 3 = <<8+8+3=19>>19 hours on work, exercise, and sleeping. Therefore he has 24 - 19 = <<24-19=5>>5 hours of free time. #### 5 An investment bank gives 10 percent interest at the end of every month. How much money in total will you have, including interest, at the end of 2 months if you invest $300? After the first month you get 10/100 * $300 = $<<10/100*300=30>>30 interest. After the first month you will have $300 + $30 = $<<300+30=330>>330 in total. After the second month you get = 10/100 * $330 = $<<10/100*330=33>>33 interest. After the second month you will have $330 + $33 = $<<330+33=363>>363 in total. #### 363 Marlon had 42 lollipops in the beginning. On his way home, he saw Emily and gave her 2/3 of his lollipops. Then, Marlon kept 4 lollipops and gave the rest to Lou. How many lollipops did Lou receive? Marlon gave Emily 42 x 2/3 = <<42*2/3=28>>28 lollipops. So, he only had 42 - 28 = <<42-28=14>>14 lollipops left. After keeping 4, Marlon gave 14 - 4 = <<14-4=10>>10 lollipops to Lou. #### 10 Julia collects old watches. She owns 20 silver watches, and three times as many bronze watches. She decided to buy gold watches to add to her collection, a number that represents 10% of all the watches she owns. How many watches does Julia own after this purchase? Julia owns 3 * 20 = <<3*20=60>>60 bronze watches. 60+20 = <<60+20=80>>80 total silver and bronze watches 10% of all Julia's watches is 80 * 10/100 = <<80*10/100=8>>8 watches, and she decided to buy so many gold watches. So in total Julia is in possession of 20 + 60 + 8 = <<20+60+8=88>>88 watches. #### 88 There were 148 peanuts in a jar. Brock ate one-fourth of the peanuts and Bonita ate 29 peanuts. How many peanuts remain in the jar? 148 * (1/4) = <<148*(1/4)=37>>37 148 - 37 - 29 = <<148-37-29=82>>82 There are 82 peanuts left in the jar. #### 82 The pizzeria sells small pizzas for $2 and large pizzas for $8.
