Question: For a school fundraiser, Chandler needs to sell 12 rolls of wrapping paper. So far, he has sold 3 rolls to his grandmother, 4 rolls to his uncle, and 3 rolls to a neighbor. How many more rolls of wrapping paper does Chandler need to sell?
Answer: Chandler has sold 3 rolls + 4 rolls + 3 rolls = 10 rolls. Chandler still needs to sell 12 rolls – 10 rolls = 2 rolls. The answer is 2.
[Question]James decides to build a tin house by collecting 500 tins in a week. On the first day, he collects 50 tins. On the second day, he manages to collect 3 times that number. On the third day, he collects 50 tins fewer than the number he collected on the second day. If he collects an equal number of tins on the remaining days of the week, what's the number of tins he collected each day for the rest of the week?
[Answer]On the second day, he collected 3 times the number of tins he collected on the first day, which is 3 * 50 = 150 tins. On the third day, he collected 50 tins fewer than the second day, which is 150 - 50 = 100 tins. The total for the three days is 150 + 100 + 50 = 300 tins. To reach his goal, he still needs 500 - 300 = 200 tins. Since the total number of days left in the week is 4, he'll need to collect 200 / 4 = 50 tins per day to reach his goal. The answer is 50.
Q: In a graveyard, there are 20 skeletons. Half of these skeletons are adult women, and the remaining number are split evenly between adult men and children. If an adult woman has 20 bones in their body, and a male has 5 more than this, and a child has half as many as an adult woman, how many bones are in the graveyard?
A: We first need to figure out how many of each type of skeleton there are. Since half the 20 skeletons are adult women, that means there are 20 / 2 = 10 adult women's skeletons. The remaining half, 10, is split between adult men and children, meaning there are 10 / 2 = 5 of each. Since an adult woman has 20 bones in their body, this means that the 10 skeletons have 20 * 10 = 200 bones in total. Since an adult man has 5 more bones in their body than an adult woman, this means they have 20 + 5 = 25 bones in their body. There are 5 adult men, meaning there are 25 * 5 = 125 bones in the adult male skeletons in total. Since a child has half as many bones as the 20 in an adult woman, this means the children have 20 / 2 = 10 bones in their body. Since there are 5 children, this means there are 5 * 10 = 50 bones in the children's skeletons in total. Therefore, altogether there are 50 + 125 + 200 = 375 bones in total in the graveyard. The answer is 375.
Question: Marla has a grid of squares that has 10 rows and 15 squares in each row. She colors 4 rows of 6 squares in the middle of the grid with red. She colors all squares on the first 2 and last 2 rows with blue. Then she colors the rest with green. How many squares does Marla color green?
Answer: There are 10 x 15 = 150 squares in a grid. 4 x 6 = 24 squares are colored red. There are 2 + 2 = 4 rows that are all blue. Thus, a total of 4 x 15 = 60 squares are colored blue. 24 + 60 = 84 squares are color red or blue. Therefore, 150 - 84 = 66 square are green. The answer is 66.
[Question]Stephanie is decorating 24 cupcakes for a birthday party, but she needs more candles. She currently has a total of 30 candles. She wants to decorate half of the cupcakes with 1 candle each and the other half of the cupcakes with 2 candles each. How many additional candles does Stephanie need to complete the cupcakes?
[Answer]For half of the cupcakes, Stephanie wants to use 1 candle each. Since half of the cupcakes is 24 / 2 and she plans to use 1 candle each for this half of the cupcakes, Stephanie needs (24 / 2) * 1 = 12 candles for this half of the cupcakes. For the other half of the cupcakes, Stephanie wants to use 2 candles. Therefore, she will need (24 / 2) * 2 = 24 candles for this half of the cupcakes. Because Stephanie needs 12 candles for half of the cupcakes and 24 candles for the other half, she needs a total of 12 + 24 = 36 candles. Since Stephanie needs 36 candles to decorate all the cupcakes and she currently has 30 candles, Stephanie needs 36 - 30 = 6 additional candles. The answer is 6.
[Question]James can buy a new computer for $600 and have it last 6 years, or buy 2 used computers for $200 each that each last 3 years. How much money will he save by picking the cheaper option?
[Answer]
First find the cost of the two used computers: $200 / computer * 2 computers = $400. Then subtract that cost from the cost of the new computer to find the savings: $600 - $400 = $200. The answer is 200.
