Alfonso earns $6 each day walking his aunt’s dog. He is saving to buy a mountain bike helmet for $340. Currently, he already has $40. If he walks his aunt's dog 5 days a week, in how many weeks should Alfonso work to buy his mountain bike?

Alfonso has to work for the $340 - $40 = $

<<300=300>>300. In a week, he earns $6 x 5 = $<<6*5=30>>30. Thus, he needs to work $300/$30 = <<300/30=10>>10 weeks to buy the bike. #### 10 A married couple and their 6 children are ordering some pizza. If the couple want 3 slices each and the children want 1 slice each, how many 4-slice pizzas should they order? The couple want 3 slices each for a total of 2*3 = <<3*2=6>>6 slices The children want 1 slice each for a total of 1*6 = <<1*6=6>>6 slices They want 6+6 = <<6+6=12>>12 slices in total Each pizza has 4 slices so they need 12/4 = <<12/4=3>>3 pizzas #### 3 Adam goes to school every day. On Monday he had 6 lessons of 30 minutes each, and on Tuesday he had 3 lessons of 1 hour each. On Wednesday, Adam spent twice as much time at school as on Tuesday. How much time in total did Adam spend at school during these 3 days, in hours? On Monday Adam had 6 * 30 = <<6*30=180>>180 minutes of lessons, which is 3 hours. On Wednesday Adam spent twice as much time at school as on Tuesday, so he spent 2 * 3 = <<2*3=6>>6 hours at school. This means that during these three days Adam spent at school 3 + 3 + 6 = <<3+3+6=12>>12 hours. #### 12 Jorge and Giuliana each eat 7 croissants for breakfast, 18 cakes after school, and 30 pizzas before bedtime. What is the total number of croissants, cakes, and pizzas the two consume in a day? The number of croissants and cakes that each eats for breakfast and lunch respectively is 7+18=<<7+18=25>>25 After eating 30 pizzas before bedtime, the number of croissants, cakes, and pizzas that each person have in total for the day is 25+30=<<25+30=55>>55 Since each person eats a total of 55 croissants, cakes, and pizzas for the day, the two consume a total of 55+55=<<55+55=110>>110 of the food in a day. #### 110 Susie babysits every day for 3 hours a day at the rate of $10 per hour. She spent 3/10 of the money she earned from last week to buy a make-up set. She then spent 2/5 of her money on her skincare products. How much is left from her earnings last week, in dollars? Susie earned $10 x 3 = $<<10*3=30>>30 per day. Last week, she earned a total of $30 x 7 = $<<30*7=210>>210. She spent $210 x 3/10 = $<<210*3/10=63>>63 on make-up. While she spent $210 x 2/5 = $<<210*2/5=84>>84 on her skincare products. Thus, she spent a total of $63 + $84 = $<<63+84=147>>147 from her earnings. Therefore, Susie is left with $210 - $147 = $<<210-147=63>>63 from her earnings last week. #### 63 Robbie is tracking his nutrition intake per week. He eats 3 cups of rice in the morning, 2 cups of rice in the afternoon, and 5 cups of rice in the evening. If a cup of rice has 10 grams of fat, how many grams of fat does Robbie get in a week? Robbie gets 3 x 10 = <<3*10=30>>30 grams of fat every morning. He gets 10 x 2 = <<10*2=20>>20 grams of fat every afternoon. And he gets 5 x 10 = <<5*10=50>>50 grams of fat every evening. So, the total grams of fat he gets every day is 50 + 30 + 20 = <<50+30+20=100>>100. Therefore, the total grams of fat he gets every week is 100 x 7 = <<100*7=700>>700. #### 700 Evie is collecting seashells while at the beach. Each day she collects her favorite 10 shells. At the end of 6 days, she gives 2 shells to her brother. How many shells does she have left? Multiply the number of shells collected each day by 6, to get the total number of seashells Evie has collected: 10 x 6 = <<10*6=60>>60 seashells Subtract the 2 shells she gave her brother, to get the number of shells she has left: 60 - 2 = <<60-2=58>>58 seashells #### 58 On Mary's birthday, her brother surprised her with $100. She spent a quarter of it on a new video game and then used a fifth of what was left on swimming goggles. How much money did she have left? Mary spent 100/4= <<100/4=25>>25 dollars on a new video game. So, after the video game purchase, Mary was left with 100 - 25 = <<100-25=75>>75 dollars. Mary then bought swimming goggles for 75/5 = <<75/5=15>>15 dollars Mary had 75 - 15 = <<75-15=60>>60 dollars left #### 60 Paul is a chicken trader. One week he had 80 chickens in total to sell at the market. Before he left the farm, he sold his neighbor 12 chickens. At the gate, before the market opens, he got a quick customer and sold another 25 chickens. How many chickens was Paul left with to sell at the market? Before the market opened, Paul sold 12 + 25 = <<12+25=37>>37 chickens So he had 80 - 37 = <<80-37=43>>43 chickens left to sell at the market. #### 43 Frank and his friends Betty and Bill went to their farm and picked oranges to eat. Betty picked 15 oranges and Bill picked 12 oranges. Frank picked three times the number that Betty and Bill picked combined. Frank then planted 2 seeds from each of his oranges into the ground and waited 20 years for each seed to turn into a beautiful orange tree. If each orange tree contains 5 oranges for Frank's son Philip to pick, how many oranges are there for Philip to pick in total? Together, Betty and Bill picked 15 + 12 = <<15+12=27>>27 oranges. Frank picked 3 * 27 = <<3*27=81>>81 oranges. Frank planted 2 * 81 = <<2*81=162>>162 seeds in total, so there are 162 orange trees 20 years later. Philip can then pick 162 * 5 = <<162*5=810>>810 oranges. #### 810
