[Question]Walter works 5 days a week in a fast-food chain and earns $5 per hour. Since he is a working student, he can only work 4 hours a day and allocates 3/4 of his weekly earning for his schooling. How much does he allocate for school?
[Answer]Walter's daily earning is $5 x 4 = $20. So he earns $20 x 5 = $100 per week. Therefore, he allocates $100 x 3 / 4 = $75 for his school. The answer is 75.
Q: Jack is ordering custom baseball caps for him and his two best friends. Jack's head is 12 inches in circumference. Charlie's head is 9 inches more than half the circumference of Jack's head. Bill's head is 2/3 the circumference of Charlie's head. How many inches in circumference is Bill's head?
A: First find half the circumference of Jack's head: 12 inches / 2 = 6 inches. Then find how big Charlie's head is: 6 inches + 9 inches = 15 inches. Then find how big Bill's head is: 15 inches * 2 / 3 = 10 inches. The answer is 10.
Question: Barney's grocery store sold out all of its items at the beginning of the pandemic, so they ordered extra items to restock the shelves. However, they ended up ordering far too much and have to keep the leftover items in the storeroom. If they ordered 4458 items, sold another 1561 items that day, and have 575 items in the storeroom, how many items do they have left in the whole store?
Answer: Barney's grocery store started with 0 items + 4458 they ordered = 4458 items total. That day they sold 1561 items, so 4458 total - 1561 sold = 2897 items. If there are 575 items in the storeroom, then there are 575 + 2897 = 3472 items in the whole store. The answer is 3472.
[Question]Alec is running for Class President. He thinks that if he can get three-quarters of the class to vote for him then there is no chance anyone else can beat him. Half of the class have already said they will vote for him but out of the remaining students, only 5 have said they are thinking about voting for him. He surveys the students who are thinking about voting for someone else, and changes his flyers to reflect the issues these students are concerned about. This results in a fifth of these students saying they'll vote for him. If Alec's class has 60 students and everyone who said they will vote for him does so, how many more votes does Alec need to reach his goal number of votes?
[Answer]To calculate Alec's goal number of votes, we need to know that 60 students / 4 = 15 students is equal to one - quarter of the class students. Alec's goal is therefore 15 students * 3 quarters = 45 votes. Half of the class said they will vote for him, so there are already 60 students / 2 = 30 votes. Another 5 students are thinking about voting for him which leaves a total so far of 30 + 5 = 35 votes. This means there are 60 students - 35 voting for Alec = 25 students not voting for Alec. A fifth of these decided to vote, so this is a further 25 students / 5 = 5 votes. Alec is therefore receiving a total of 35 + 5 = 40 votes. So he has missed his goal by 45 goal votes - 40 actual votes = 5 votes. The answer is 5.
Q: Diana earned $150 in July. She earned 3 times this amount in August. In September, She earned twice the money she earned in August. How much money did Diana earn over these three months?
A: The amount of money Diana earned in August is 3 * $150 = $450. The amount of money Diana earned in September is 2 * $450 = $900. The total amount of money Diana earned over the three months is $150 + $450 + $900 = $1500. The answer is 1500.
Question: John uses 5 liters of fuel per km to travel. How many liters of fuel should John plan to use if he plans to travel on two trips of 30 km and 20 km?
Answer:
The first trip will use 30 * 5 = 150 liters of fuel. The second trip will use 20 * 5 = 100 liters of fuel. The total liters of fuel are 150 + 100 = 250 liters. The answer is 250.
