Q: Tammy just got her hair cut. For every 14 haircuts, she gets a free additional haircut. She has gotten 5 free haircuts already. She is 5 haircuts away from another free one. How many haircuts has she gotten there?
A: She has gotten 70 haircuts to get 5 free ones because 14 x 5 = 70. She has gotten 9 haircuts towards her 6th free one because 14 - 5 = 9. She has gotten 79 haircuts because 70 + 9 = 79. The answer is 79.
Question: The teacher told the class that if they averaged at least 75% on their final exam, they could have a pizza party. Everyone took the exam on Monday, except for William, who was allowed to take it on Tuesday. If there are 30 people in the class, and the average before he took the test was a 74%, what score does he have to get to make sure they get to have a pizza party?
Answer: Let x be the score that William needs to achieve. Since there are 30 people in the class, there are 30 - 1 = 29 people without him. Since their average was a 74%, this means that (29 * 74 + x) / 30 > = 75. Thus, 29 * 74 + x > = 30 * 75. Thus, 29 * 74 + x > = 2250. Thus, 2146 + x > = 2250. Thus, x > = 2250 - 2146. Thus, x > = 94. The answer is 94.
[Question]Chris is trying to sell his car for $5200 and has gotten two price offers. One buyer offered to pay the full price if Chris would pay for the car maintenance inspection, which cost a tenth of Chris’s asking price. The other buyer agreed to pay the price if Chris replaced the headlights for $80 and the tires for three times as much. What is the difference between the amounts Chris will earn from the two offers?
[Answer]Chris would earn 5200 - 5200 / 10 = 5200 - 520 = $4680 from the first buyer. He would earn 5200 - 80 - 80 * 3 = 5200 - 80 * 4 = 5200 - 320 = $4880 from the second buyer. The difference between Chris’s earnings would be 4880 - 4680 = $200. The answer is 200.
Q: While Paul watches movies, he runs on his treadmill. He can run a mile in 12 minutes. He watches two movies, which are an average length of 1.5 hours. How many miles does he run?
A: He runs for 3 hours because 2 x 1.5 = 3. He runs for 180 minutes because 3 x 60 = 180. He runs 15 miles because 180 / 12 = 15. The answer is 15.
Question: After tests in California, the total number of Coronavirus cases was recorded as 2000 positive cases on a particular day. The number of cases increased by 500 on the second day, with 50 recoveries. On the third day, the total number of new cases spiked to 1500 with 200 recoveries. What's the total number of positive cases after the third day?
Answer:
When 500 new cases were recorded after the tests, the total number of positive cases increased to 2000 cases + 500 cases = 2500 cases. With 50 recoveries, the total number of cases reduced to 2500 cases - 50 cases = 2450 cases. On the third day, with 1500 new cases, the total number of cases became 2450 cases + 1500 cases = 3950 cases. If 200 people recovered from the virus, the total number of people with Coronavirus became 3950 cases - 200 cases = 3750 cases. The answer is 3750.
