[Question]Jett bought a cow from the market at $600 and took it to his farm. He spent $20 every day to buy food. He also used $500 to vaccinate and deworm the cow. If he sold the cow for $2500 after 40 days, calculate the profit he made from selling back the cow to the market.
[Answer]The total cost of food that the cow ate for the forty days is 40 * $20 = $800. To feed and maintain the health of the cow, the total expenses Jett used is $500 + $800 = $1300. With the expenses, Jett used $1300 + $600 = $1900 on the cow. If he sold the cow at $2500, Jett made a profit of $2500 - $1900 = $600. The answer is 600.
Q: A survey was conducted by a school to the parents about their children's online class experience. Fifteen percent of the respondents rated Excellent; 60% rated Very Satisfactory; 80% of the remaining respondents rated Satisfactory and the rest rated Needs Improvement. If 120 parents answered the survey, how many of them rated Needs Improvement?
A: The total percentage of those who rated Excellent or Very Satisfactory is 15% + 60% = 75%. Seventy - five percent of the parents is 120 x 75 / 100 = 90. Hence, 120 - 90 = 30 students rated either Satisfactory or Needs Improvement. A total of 30 x 80 / 100 = 24 parents rated Satisfactory. Therefore, 30 - 24 = 6 parents rated Needs Improvement. The answer is 6.
Question: Part of Stella's job is to restock the toilet paper in each of the 6 bathrooms at the bed and breakfast. She stocks 1 roll a day, every day of the week. She buys the toilet paper in bulk, and each pack contains 1 dozen rolls. After 4 weeks, how many packs of toilet paper dozen Stella buy?
Answer: She stocks one roll in each of the 6 bathrooms, every day of the week so that 6 * 7 = 42 rolls a week. She restocks 42 rolls a week so after 4 weeks that's 42 * 4 = 168 rolls. The bulk toilet paper comes 1 dozen rolls in a pack and she needs 168 rolls so she needs 168 / 12 = 14 dozen. The answer is 14.
[Question]Karlee has 100 grapes and 3/5 as many strawberries as grapes. Giana and Ansley, two of her friends, come visiting, and she gives each of them 1/5 of each fruit. How many fruits is Karlee left with in total?
[Answer]If Karlee has 3 / 5 times as many strawberries as grapes, she has 3 / 5 * 100 grapes = 60 strawberries. When her friends come over, she gives each of them 1 / 5 * 100 grapes = 20 grapes. In total, she gives out to her two friends 2 friends * 20 grapes / friend = 40 grapes. She's left with 100 grapes - 40 grapes = 60 grapes. She also gives each of her friends 1 / 5 * 60 strawberries = 12 strawberries. In total, she gives her two friends 2 friends * 12 strawberries / friend = 24 strawberries. She's left with 60 strawberries - 24 strawberries = 36 strawberries. The total number of fruits Karlee remains with is 36 strawberries + 60 grapes = 96 fruit. The answer is 96.
Q: While bird watching, Gabrielle saw 5 robins, 4 cardinals, and 3 blue jays. Chase saw 2 robins, 3 blue jays, and 5 cardinals. How many more birds, in percentage, did Gabrielle saw than Chase?
A: Gabrielle saw 5 + 4 + 3 = 12 birds. Chase saw 2 + 3 + 5 = 10 birds. So, Gabrielle saw 12 - 10 = 2 more birds than Chase. Therefore, Gabrielle saw 2 / 10 x 100% = 20% more birds than Chase. The answer is 20.
