Question: Thomas is keeping track of the rainfall in May for his science project. On the first day, 26 cm of rain fell. On the second day, 34 cm fell. On the third day, 12 cm less than the second day fell. The average rainfall for the first three days of May is usually 140 cm across all three days, in a normal year. How much less is it raining this year than average?
Answer: In total 26 + 34 + 22 = 82 cm fell for three days. If 140 cm is the average for the first three days, then 140 - 82 = 58 cm less than the average. The answer is 58.
[Question]Three schools organized a science fair competition and invited students from all the schools to develop ideas and present them before a panel of judges selected by all the schools competing in the science fair. There were 50 students from Know It All High School at the competition, 3/5 times as many students from Karen High as Know It All High School, and twice the combined number of students from the first two schools that came were from Novel Corona High School. Calculate the total number of students at the competition?
[Answer]If 50 students came from Know It All High School, then Karen High, which had 3 / 5 times as many students as Know It All High School, had 3 / 5 * 50 = 30 students at the fair. The total number of students from Know It All and Karen high schools is 50 + 30 = 80 students. If Novel Corona had twice the combined number of students from Know It All and Karen high schools, then it had 2 * 80 = 160 students at the competition. The total number of students at the competition is 80 + 160 = 240. The answer is 240.
Q: James buys jars for his honey. He has 5 hives that each produce 20 liters of honey. Each jar can hold .5 liters. How many jars will he need to buy if his friend is bringing his own jars for half the honey?
A: He produces 5 * 20 = 100 liters of honey. That means he keeps 100 / 2 = 50 liters of honey. So he needs 50 / .5 = 100 jars. The answer is 100.

[Question]Since 1989, Lily has treated herself to 1 hydrangea plant, each year. Each plant costs $20.00. By 2021, how much money has Lily spent on hydrangeas?
[Answer]She started buying plants in 1989 and it's now 2021 so she has bought these plants for 2021 - 1989 = 32 years. Each plant costs $20.00 and she has bought them for 32 years so she has spent 20 * 32 = $640.00 on hydrangeas. The answer is 640.
[Question]The Giants baseball team is trying to make their league playoff. They have played 20 games and won 12 of them. To make the playoffs, they need to win 2/3 of their games over the season. If there are 10 games left, how many do they have to win to make the playoffs?
[Answer]
There are 30 games total because 20 + 10 = 30. They need to win 20 games because 30 x (2 / 3) = 20. The need to win 8 more games because 20 - 12 = 8. The answer is 8.
