[Question]There are 11 boys and 13 girls in a class. If 1 boy is added to the class, what percentage of the class are girls?
[Answer]There are a total of 11 + 1 = 12 boys in the class. Hence, there are a total of 12 boys + 13 girls = 25 students in a class. So 13 / 25 x 100% = 52% of the class are girls. The answer is 52.
Q: Dennis wants to buy 4 pairs of pants from the store which cost $110.00 each with a 30% discount and he also wants to buy 2 pairs of socks which cost $60.00 with a 30% discount. How much money will Dennis have to spend in total after he bought all the items he wants after the discount?
A: Dennis wants to buy 4 pairs of pants which cost 110x4 = $440. And he also wants to buy 2 pairs of socks that cost 60x2 = $120. The total amount he needs to spend without the discount is 440 + 120 = $560. The discount he will have amounts to $560x.0.30 = $168.00. So the total amount he needs to spend after deducting the discount from the total amount is 560 - 168 = $392. The answer is 392.
Question: A Moroccan restaurant received 3 different shipments of couscous. The first two shipments of 7 and 13 pounds arrived on the same day. The next day's shipment was 45 pounds of couscous. If it takes 5 pounds of couscous to make a dish, how many dishes did the restaurant make?
Answer: The first two shipments of couscous added up to 7 + 13 = 20 pounds. Adding that weight to the next day’s shipment results in a total weight of 20 + 45 = 65 pounds. Since each dish takes 5 pounds, then the restaurant makes 65 / 5 = 13 dishes. The answer is 13.
[Question]Jane is dividing up minnows to be carnival prizes. She bought 600 minnows, and each prize is a bowl with 3 minnows. If 800 people are going to play the game and 15% win a prize, how many minnows will be left over?
[Answer]First find the number of people that win a prize: 800 people * 15% = 120 people. Then multiply that number by the number of minnows each person wins: 120 people * 3 minnows / person = 360 minnows. Then subtract that number of minnows won from the starting number to find the number that are left: 600 minnows - 360 minnows = 240 minnows. The answer is 240.
Q: Ben has $2000 for his business operations costs. He orders goods from his supplier and writes them a cheque for $600. His debtor pays him $800 from the purchases they had made on credit. Mr. Ben then decides to do equipment maintenance and spends $1200 on the whole operation. How much money is Mr. Ben remaining with?
A: When Mr. Ben writes the cheque, he remains with $2000 - $600 = $1400. His debtor pays him $800, increasing his operation capital to $1400 + $800 = $2200. He spends $1200, remaining $2200 - $1200 = $1000 for business operations cost after maintenance. The answer is 1000.
Question: In Fred the Farmer's barn, there were 100 horses, 29 sheep, and 9 chickens. Brian bought half of the animals and sold them at the market. Jeremy then gifted Fred an additional 37 goats. If exactly half of the animals in the barn are male animals, how many male animals are there in the barn?
Answer:
Fred's barn started with 100 + 29 + 9 = 138 animals. Brian bought half of these, so there were 138 / 2 = 69 remaining. After Jeremy gifted Fred 37 goats, there were 69 + 37 = 106 animals in the barn. So, 106 / 2 = 53 of these animals are male. The answer is 53.
