Q: A seminar is offered to a school for their teachers. The regular seminar fee is $150 but they offer a 5% discount if they register 2 days before the scheduled seminar. The school registered 10 teachers for the seminar a week before the schedule and it also released a $10 food allowance for each of the teachers. How much did the school spend in all?
A: The school got a $150 x 5 / 100 = $7.50 seminar fee discount for each teacher. Each teacher's seminar fee costs $150 - $7.50 = $142.50. So, ten teachers' seminar fees cost $142.50 x 10 = $1425. The food allowance for 10 teachers amounts to $10 x 10 = $100. Therefore, the school spent a total of $1425 + $100 = $1525. The answer is 1525.
Question: Ali's class wants to order 35 English textbooks and 35 geography textbooks. Knowing that a geography book costs $10.50 and that an English book costs $7.50, what is the amount of this order?
Answer: The cost of the geography books is 35 * 10.5 = $367.5. The cost of the English books is 35 * 7.5 = $262.5. The total amount of the order is 367.5 + 262.5 = $630. The answer is 630.
[Question]Millie, Monica, and Marius are taking subjects for school. Millie takes three more subjects than Marius, who takes 4 subjects more than Monica. If Monica took 10 subjects, how many subjects all take altogether?
[Answer]If Monica took ten subjects, Marius took 10 + 4 = 14 subjects. Marius and Monica have 14 + 10 = 24 subjects which they've taken. Since Millie is taking three more subjects than Marius, she is taking 14 + 3 = 17 subjects. Together, the three have taken 24 + 17 = 41 subjects. The answer is 41.
Q: Dan's skateboarding helmet has ten more craters than Daniel's ski helmet. Rin's snorkel helmet has 15 more craters than Dan's and Daniel's helmets combined. If Rin's helmet has 75 craters, how many craters are in Dan's helmet?
A: If Rin's snorkel helmet has 75 craters, then Dan's and Daniel's helmets combined have 75 - 15 = 60 craters. Let's assume Dan's helmet has C craters. Since Dan's skateboarding helmet has ten more craters than Daniel's ski helmet, the total number of craters their helmets have is C + (C - 10) = 60. 2C = 60 + 10. The total number of craters that Dan's helmet has is C = 70 / 2. Dan's skateboarding helmet has 35 craters. The answer is 35.
Question: To upgrade her kitchen, Amanda is changing out the doorknobs/pulls. She's replacing 18 cabinet knobs, which cost $2.50 each and 8 drawer pulls which cost $4.00. How much will the kitchen upgrade cost her?
Answer: She's replacing 18 cabinet knobs for $2.50 each for a total of 18 * 2.50 = $45.00. She's replacing 8 drawer pulls for $4.00 each for a total of 8 * 4 = $32.00. The cabinet knobs will cost $45.00 and the pulls will cost $32.00 for a total of 45 + 32 = $77.00 in upgrades. The answer is 77.
Q: Carmen needs $7 more to have twice the amount of money that Jethro has. Meanwhile, Patricia has $60, which is 3 times as much as Jethro. What is the sum of all their money?
A:
Jethro has 60 / 3 = $20. Twice of what Jethro has is $20 x 2 = $40. Carmen has $40 - 7 = $33. The sum of all their money is $60 + $20 + $33 = $113. The answer is 113.
