All people named Barry are nice, while only half of the people named Kevin are nice. Three-fourths of people named Julie are nice, while 10% of people named Joe are nice. If a crowd contains 24 people named Barry, 20 people named Kevin, 80 people named Julie, and 50 people named Joe, how many nice people are in the crowd?
Let's think: If all people named Barry are nice, and the crowd contains 24 people named Barry, then 1 * 24 = 24 of these people are nice. If only half of people named Kevin are nice, and the crowd contains 20 people named Kevin, then 0.5 * 20 = 10 of these people are nice. If three - fourths of people named Julie are nice, and the crowd contains 80 people named Julie, then (3 / 4) * 80 = 60 of these people are nice. If 10% of people named Joe are nice, and the crowd contains 50 people named Joe, then 0.1 * 50 = 5 of these people are nice. In total, the crowd contains 24 + 10 + 60 + 5 = 99 people who are nice.. The answer is: 99.

Lizette scored 92 on her third quiz giving her an average of 94. What is Lizette's average in her first two quizzes?
Let's think: If Lizette's average on the 3 quizzes is 94, then the sum of her scores in the 3 quizzes is 94 x 3 = 282. This means that the sum of her scores in the first 2 quizzes is 282 - 92 = 190. Thus, her average for the first 2 quizzes is 190 / 2 = 95.. The answer is: 95.

Sabrina is collecting herbs to make a poultice for her grandmother. She needs twice as many basil leaves as sage leaves and 5 fewer sage leaves than verbena leaves. If she needs 12 basil leaves, how many leaves total does she need?
Let's think: First find the number of sage leaves Sabrina needs: 12 basil / 2 basil / sage = 6 sage. Then add 5 to find the total number of verbena leaves she needs: 6 sage + 5 = 11 verbena. Finally, add up all the different leaves to find the total number: 6 sage + 11 verbena + 12 basil = 29 leaves.. The answer is: 29.

Natalia is riding a bicycle for the cycling competition. On Monday she rode 40 kilometers and on Tuesday 50 kilometers. On Wednesday she rode 50% fewer kilometers than the day before. On Thursday she rode as many as the sum of the kilometers from Monday and Wednesday. How many kilometers did Natalie ride in total?
Let's think:
On Wednesday she covered half of the distance from Tuesday, so 50 / 2 = 25 kilometers. On Thursday she rode 40 + 25 = 65 kilometers. In total, Natalia rode 40 + 50 + 25 + 65 = 180 kilometers.. The answer is: 180.
