[Question]Louis is making himself a velvet suit for a formal event. The velvet fabric he chose was $24 per yard. He bought a pattern for $15, and two spools of silver thread for $3 each. If he spent $141 for the pattern, thread, and fabric, how many yards of fabric did he buy?
[Answer]Let V be the number of yards of velvet fabric Louis bought. The silver thread cost 2 * 3 = $6. He spent 24V + 15 + 6 = $141 on the suit. The fabric cost 24V = 141 - 15 - 6 = $120. Thus, Louis bought V = 120 / 24 = 5 yards of fabric. The answer is 5.
Q: John's new computer cost $1500. He needs to get a monitor and other peripherals that cost 1/5 that much. He also wants to upgrade the $300 video card in the base computer with one that costs twice as much. How much did he spend?
A: The peripherals cost 1500 / 5 = $300. The video card cost 300 * 2 = $600. So it cost 600 - 300 = $300 more. That means the total cost was 1500 + 300 + 300 = $2100. The answer is 2100.

Q: A tank can hold 100 liters of water. At the beginning of the rainy season, the tank is 2/5 filled with water. On the first day of the rainy season, the tank collected 15 liters of water. On the second day, 5 liters more water was collected than on the first day. On the third day, the tank was already filled. How many liters of water were collected on the third day?
A: At the beginning of the rainy season, the tank is filled with 100 x 2 / 5 = 40 liters of water. On the first day of the rainy season, the tank had 40 + 15 = 55 liters of water. On the second day, 15 + 5 = 20 liters of water were collected. So, the tank is filled with 55 + 20 = 75 liters of water on the second day. Therefore, 100 - 75 = 25 liters of water were collected on the third day. The answer is 25.
Question: Erwan went on shopping. He purchased a pair of shoes at $200 but discounted 30%, and two shirts at $80 each. Upon checkout, the cashier said that there is an additional 5% discount. How much did he spend after all the discounts?
Answer:
The total discount of a pair of shoes is $200 x 30 / 100 = $60. He spent $200 - $60 = $140 for a pair of shoes. The total cost of two shirts is $80 x 2 = $160. The initial cost of his purchase is $140 + $160 = $300. He got an additional $300 x 5 / 100 = $15 discount upon checkout. Therefore, Erwan spent $300 - 15 = $285 after all the discounts. The answer is 285.
