Claire wants to make 2 cakes for her mother. Two packages of flour are required for making a cake. If 1 package of flour is $3, how much does she pay for the flour that is enough to make 2 cakes?

She needs 2*2=

<<2*2=4>>4 packages of flour for 2 cakes. 4 packages of flour cost 4*$3=$<<4*3=12>>12. #### 12 Ann is 6 years old. Her brother Tom is now two times older. What will be the sum of their ages 10 years later? Tom is currently two times older than Ann, which means he is 6 * 2 = <<6*2=12>>12 years old. In ten years Ann is going to be 6 + 10 = 16 years old. And Tom is going to be 12 + 10 = <<12+10=22>>22 years old. So the sum of their ages will be 16 + 22 = <<16+22=38>>38. #### 38 James gets bored with his game so decides to play a different one. That game promises 100 hours of gameplay but 80% of that is boring grinding. However, the expansion does add another 30 hours of enjoyable gameplay. How much enjoyable gameplay does James get? The first game was 100*.8=<<100*.8=80>>80 hours of grinding So it was 100-80=<<100-80=20>>20 hours of good gameplay The expansion brought the time of good gameplay to 20+30=<<20+30=50>>50 hours #### 50 Alden had 50 nephews ten years ago. This is half the number of nephews Alden has now. If Vihaan has 60 more nephews than Alden now, how many nephews do the two have altogether? If the number of nephews Alden had 50 years ago is half the number of nephews he has now, Alden has 50*2 = <<50*2=100>>100 nephews. Vihaan has 60 more nephews than Alden, meaning currently Vihaan has 100+60 = <<100+60=160>>160 nephews. Altogether, the two have 160+100 = <<160+100=260>>260 nephews. #### 260 Elsie has a specific amount of wet wipes in a container in the morning. Throughout the day, she refills the container with 10 more wipes after using up 20. By nighttime, she only has 60 wipes left. How many wipes were in the container in the morning? Let w be the number of wet wipes Elsie had in the morning. Throughout the day, she used w-20 wet wipes. Once that happened, she had to refill the container resulting in w-20+10 = w<<-20+10=-10>>-10 wet wipes. By nighttime, she had w-10=60 wipes. So then, w=60+10=<<60+10=70>>70. She started with w=<<70=70>>70 wipes. #### 70 One necklace is worth $34. Bob decided to buy one for his wife. But, he also bought a book, which is $5 more expensive than the necklace. Before he went shopping, Bob set a limit and decided not to spend more than $70. How many dollars over the "limit" did Bob spend? The book is $5 more expensive than the necklace, which means the book costs 34 + 5 = $<<34+5=39>>39. Both products which Bob wants to buy cost in total 39 + 34 = $<<39+34=73>>73. So Bob will spend 73 - 70 = $<<73-70=3>>3 over the limit. #### 3 Tom has only been getting 6 hours of sleep a day. He increases that by 1/3. How many hours of sleep does he get per night? He increases his sleep by 6/3=<<6/3=2>>2 hour per night So he now gets 6+2=<<6+2=8>>8 hours of sleep per night #### 8 Sadie, Ariana and Sarah are running a relay race. Each part of the race is a different length and covers different terrain. It takes Sadie 2 hours to run through the forest at an average speed of 3 miles per hour. Ariana sprints across the open field on her section at 6 miles per hour for half an hour. If Sarah runs along the beach at four miles per hour and their total time for the race is four and half hours, what is the total distance of the race? Sadie ran for 3 miles/hour * 2 hour = <<3*2=6>>6 miles. Ariana covered a distance of 6 miles/hour * (1/2) hour = 3 miles. Sarah ran for 4.5 hours – 2 hours – 0.5 hours = <<4.5-2-0.5=2>>2 hours. In this time, Sarah traveled a distance of 4 miles/hour * 2 hours = <<4*2=8>>8 miles. The total distance for the race was 6 miles + 3 miles + 8 miles = <<6+3+8=17>>17 miles. #### 17 A company has 1000 employees. There will be three rounds of layoffs. For each round of layoff, 10% of the remaining employees will be laid off. How many employees will be laid off in total? The first round will result in 1000 * 10% = <<1000*10*.01=100>>100 employee layoffs. There are 1000 - 100 = <<1000-100=900>>900 employees remaining. The second round will result in 900 * 10% = <<900*10*.01=90>>90 employee layoffs. There are 900 - 90 = <<900-90=810>>810 employees remaining. The third round will result in 810 * 10% = <<810*10*.01=81>>81 employee layoffs. The total number of of employees laid off is 100 + 90 + 81 = <<100+90+81=271>>271. #### 271 Sam spends sixty minutes studying Science, eighty minutes in Math, and forty minutes in Literature. How many hours does Sam spend studying the three subjects? The total number of minutes he studies the three subjects is 60 + 80 + 40 = <<60+80+40=180>>180 minutes. Therefore, Sam spends 180/60 = <<180/60=3>>3 hours. #### 3
