[Question]Celine collected twice as many erasers as Gabriel did. Julian collected twice as many erasers as Celine did. If they collected 35 erasers in total, how many erasers did Celine collect?
[Answer]Let x represent the number of erasers Gabriel collected. Celine collected 2 * x erasers. Julian collected 2 * x * 2 = 4 * x erasers. In total, Gabriel, Celine and Julian collected x + 2 * x + 4 * x = 7 * x erasers. 7 * x = 35. x = 5. Celine collected 5 * 2 = 10 erasers. The answer is 10.
Q: Mason is a caterer packing up silverware and plates for a big corporate event. Each piece of silverware weighs 4 ounces, and there are three pieces of silverware per setting. Each plate weighs 12 ounces, and there are two plates per setting. If Mason needs enough settings for 15 tables with 8 settings each, plus 20 backup settings in case of breakage, how many ounces will all the settings weigh?
A: First find the total weight of the silverware per setting: 4 ounces / piece * 3 pieces / setting = 12 ounces / setting. Then find the total weight of the plates per setting: 12 ounces / plate * 2 plates / setting = 24 ounces / setting. Then add those two amounts to find the total weight per setting: 12 ounces / setting + 24 ounces / setting = 36 ounces / setting. Then multiply the number of tables by the number of settings per table to find the number of table settings: 15 tables * 8 settings / table = 120 settings. Then add the 20 backup settings to find the total number of settings: 120 settings + 20 settings = 140 settings. Then multiply the total number of settings by the weight per setting to find the total weight: 140 settings * 36 ounces / setting = 5040 ounces. The answer is 5040.
Question: Mark has kangaroos and goats. Kangaroos have two legs and goats have four legs. If he has 23 kangaroos and three times as many goats as kangaroos what is the total number of legs of all his animals?
Answer: His kangaroos have a total of 23 * 2 = 46 legs. He has 23 * 3 = 69 goats. The goats have 69 * 4 = 276 legs. So in total his animals have 276 + 46 = 322 legs. The answer is 322.
[Question]Two-fifths of the seats in an auditorium that holds 500 people are currently taken. It was found that 1/10 of the seats are broken. How many seats are still available?
[Answer]500 / 2 / 5 = 200 seats are already taken. 500 / 1 / 10 = 50 seats are broken. So 200 + 50 = 250 seats are either taken or broken. Therefore, 500 - 250 = 250 seats are still available. The answer is 250.
[Question]Martin went to a store to buy a new television set. He decided to spend no more than $1,000 and the sales clerk offered him the TV for $100 less and an additional 20% off. How much lower was the price of the television than the amount Martin decided to spend?
[Answer]
The seller has offered him the TV for 1000 - 100 = $900. The discount on the television was 900 * 20 / 100 = $180. The final price of the television is therefore 900 - 180 = $720. Martin was able to save 1000 - 720 = $280. The answer is 280.
