Q: A party venue has 4 tables that seat 6 people each, 16 tables that seat 4 people each, and 8 round tables that seat 10 people each. What is the total capacity of all the tables at the party venue?
A: Four 6 - seater tables can accommodate 4 x 6 = 24 people. Sixteen 4 - seater tables can accommodate 16 x 4 = 64 people. Eight 10 - seater table can accommodate 8 x 10 = 80 people. Therefore, all the tables in the party venue can accommodate 24 + 64 + 80 = 168 people. The answer is 168.

Q: Lily goes to the supermarket. She has $60. She needs to buy 6 items: celery, cereal, bread, milk, potatoes, and coffee. She finds a stalk of celery for $5, cereal for 50% off $12, bread for $8, and milk for 10% off $10. She finds potatoes for $1 each and buys 6. How many dollars does she have left to spend on coffee?
A: Lily spends $5 + $8 = $13 on celery and bread. Lily spends $12 * (50 / 100) = $6 on cereal. Lily gets 10% off the milk, so she pays 100% - 10% = 90% of its original price. Lily spends $10 * 90% = $9 on milk. She spends $1 * 6 = $6 on potatoes. Thus, she has $60 - $13 - $6 - $9 - $6 = $26 left over for coffee. The answer is 26.

Q: David swims the 100-meter freestyle in 48 seconds. He swims the 100-meter backstroke 4 seconds slower than he swims the 100-meter freestyle, he swims the 100-meter butterfly 3 seconds slower than he swims the 100-meter backstroke, and he swims the 100-meter breaststroke 2 seconds slower than he swims the 100-meter butterfly. What is the combined length of time, in seconds, it would take for him to swim all four 100-meter events (the freestyle, the backstroke, the butterfly, and the breaststroke)?
A:
David swims the 100m backstroke at 48 + 4 = 52 seconds. He swims the 100m butterfly at 52 + 3 = 55 seconds. He swims the 100m breaststroke at 55 + 2 = 57 seconds. IN total, it would take David 48 + 52 + 55 + 57 = 212 seconds. The answer is 212.
