[Question]Carl buys index cards for his class. He gives each student 10 index cards. He teaches 6 periods a day and each class has 30 students. If a 50 pack of index cards cost $3 how much did he spend on them all?
[Answer]He has 30 * 6 = 180 students. So he needs to buy 180 * 10 = 1800 index cards. That means he needs to buy 1800 / 50 = 36 packs of index cards. So he spends 36 * 3 = $108. The answer is 108.
Q: Ms. Mitsuko told the class that if the average score on their quiz is higher than 75% then they will get a pizza party. There are 25 students in the class. One student is absent and has to take the test the next day. The average score of the students who took the test was 77%. What is the lowest grade the absent student can get for the class to still get a pizza party?
A: The total percentage the class needs to get is 18.75 because 25 x .75 = 18.75. The total percentage the class has absent the one student is 18.48. The lowest the absent student can get and still have a pizza party is 27% because (18.75 - 18.48)x 100 = 27. The answer is 27.
Question: Carl has a goal of selling 96 cupcakes in 2 days. Carl needs to give 24 cupcakes to Bonnie as payment for using her storefront. How many cupcakes must Carl sell per day to reach his goal?

[Question]Bobby received his weekly paycheck today. Although his salary is $450 per week, his actual paycheck is reduced in size because there are some taxes, insurance payments, and fees removed from his pay before his employer writes the check. If the government removes 1/3 in federal taxes and 8% in state taxes, the health insurance removes $50 per week, the life insurance removes $20 per week, and the city charges him a fee of $10 per week for parking, then what is the final amount left in Bobby's paycheck, in dollars?
[Answer]The federal government takes out 1 / 3 * 450 = 150 dollars. The state takes out 0.08 * 450 = 36 dollars. Then the final amount remaining after all the deductions are removed is 450 - 150 - 36 - 50 - 20 - 10 = 184 dollars. The answer is 184.
Q: In a classroom, there are blue chairs, green chairs, and white chairs. There are 10 blue chairs. The green chairs are 3 times as many as the blue chairs, and there are 13 fewer white chairs than the green and blue chairs combined. How many chairs are there in a classroom?
A: There are 10 x 3 = 30 green chairs. The total number of blue and green chairs is 10 + 30 = 40. So, there are 40 - 13 = 27 white chairs. Therefore, there are 40 + 27 = 67 chairs in a classroom. The answer is 67.
Question: It's Yvette's turn to treat herself and her three best friends to a round of ice cream sundaes. Alicia orders the peanut butter sundae for $7.50. Brant orders the Royal banana split sundae for $10.00. Josh orders the death by chocolate sundae for $8.50 and Yvette orders the cherry jubilee sundae for $9.00. She leaves her waiter a 20% tip. How much will her final bill be?
Answer:
Yvette spent 7.50 + 10 + 8.5 + 9 = $35.00 on ice cream sundaes. Her bill comes to $35.00 and she leaves a 20% tip for the waiter so that's 35 * .20 = $7.00. The bill was $35.00 and she added a $7.00 tip for a total of 35 + 7 = $42.00. The answer is 42.
