Question: 1/3 of the townspeople have received the full COVID vaccine. 1/3 are immune because they already recovered from COVID. If 1/6 of the townspeople are both vaccinated and already had COVID, what percent of the town is immune in some way?
Answer: First add the fractions of vaccinated and recovered townspeople: 1 / 3 + 1 / 3 = 2 / 3. Then you need to subtract the fraction that are both vaccinated and recovered, since they were double - counted. To do this, start by converting 2 / 3 to the same denominator as 1 / 6: 2 / 3 * 2 / 2 = 4 / 6. Then subtract 1 / 6 from 4 / 6: 4 / 6 - 1 / 6 = 3 / 6. Then divide the numerator by the denominator and multiply by 100% to express the answer as a percentage: 3 / 6 * 100% = 50%. The answer is 50.

Question: A busy restaurant is counting how many customers they had during that Friday to try to predict how many they might get on Saturday. During breakfast, they had 73 customers. During lunch, they had 127 customers. During dinner, they had 87 customers. If they predict they'll get twice the amount of customers on Saturday as they had on Friday, how many customers do they predict they will get?
Answer: On Friday the restaurant had 73 customers for breakfast + 127 customers for lunch + 87 customers for dinner = 287 customers total on Friday. If they predict getting 2x the amount of customers on Saturday as on Friday, they will have 287 customers x 2 = 574 customers on Saturday. The answer is 574.
[Question]Jordan noticed that there are 2 cars in his driveway that each have 4 wheels. There are 2 bikes and a trash can that each have 2 wheels. There is also a tricycle and a pair of old roller skates. How many wheels are there?
[Answer]There are 2 cars with 4 wheels each so that's 2 * 4 = 8 wheels. Two bikes and a trash can each have 2 wheels so that's 3 * 2 = 6 wheels. Each roller skate has 4 wheels and there is a pair, which means 2 skates for a total of 4 * 2 = 8 wheels. Including the 3 wheels on the tricycle, there are 8 from the car, 6 from bikes and a trashcan and 8 from roller skates for a total of 3 + 8 + 6 + 8 = 25 wheels. The answer is 25.
