[Question]June’s class has 25 students. 60% are girls and the rest are boys. 40% of the boys like playing basketball and the rest don't. The number of girls who like playing basketball is double the number of boys who don't like to. What percentage of the girls in the class like playing basketball?
[Answer]40% of the class is boys because 100 - 60 = 40. There are 10 boys because 25x.4 = 10. 60% of the boys don't like playing basketball because 100 - 40 = 60. 6 boys don't like playing basketball because 10x.6 = 6. 12 girls like playing basketball because 6x2 = 12. There are 15 girls in the class because 25 - 10 = 15. 80% of the girls in class like playing basketball because 12 / 15 = .8. The answer is 80.

[Question]The difference between the price of an orange and the price of a pear equals the price of a banana. If the total cost of an orange and a pear is $120 and a pear costs $90, calculate the total price of buying 200 bananas and twice as many oranges as bananas.
[Answer]If the total cost of an orange and a pear is $120, and a pear costs $90, an orange costs $120 - $90 = $30. Since the difference between the price of an orange and a pear is the price of a banana, a banana is sold at $90 - $30 = $60. To buy 200 bananas, you'll pay $60 * 200 = $12000. When you twice as many oranges as bananas, you buy 2 * 200 = 400 oranges. The total cost of buying 400 oranges is 400 * 30 = $12000. The total price of buying 200 bananas and twice as many oranges as bananas is $12000 + $12000 = $24000. The answer is 24000.

[Question]Ian used a grocery delivery app to have his groceries delivered. His original order was $25 before delivery and tip. He noticed that 3 items changed on his order. A $0.99 can of tomatoes was replaced by a $2.20 can of tomatoes, his $1.00 lettuce was replaced with $1.75 head of lettuce and his $1.96 celery was replaced with celery that cost $2.00. Delivery and tip came to a total of $8.00. How much is his new bill now, with the food substitutes and delivery/tip?
[Answer]He ordered a can of tomatoes for $0.99 but they subbed with one that cost $2.20 for a difference of 2.20 - .99 = $1.21. He ordered lettuce for $1.00 but they subbed with one that cost $1.75 for a difference of 1.75 - 1.00 = $0.75. His celery for $1.96 but they subbed with one that cost $2.00 for a difference of 2.00 - 1.96 = $0.04. That's an additional charge of 1.21 + .75 + .04 = $2.00 in groceries. His additional charges of $2.00 and the delivery / tip of $8.00 add 2 + 8 = $10.00 to the order. His original order was $25 and they added $10.00 so his new order is 25 + 10 = $35.00. The answer is 35.
