Question: A normal lemon tree produces 60 lemons per year. Jim has specially engineered lemon trees that produce 50% more lemons per year. He has a grove that is 50 trees by 30 trees. How many lemons does he produce in 5 years?
Answer with step-by-step thinking: Each tree produces 60 * .5 = 30 more lemons than normal. So they each produce 60 + 30 = 90 lemons. He has 50 * 30 = 1500 trees. So every year he produces 1500 * 90 = 135000 lemons. That means he produces 135000 * 5 = 675,000.
So the answer is 675000.


Question: Kwame studied for the history test for 2.5 hours. Connor studied for 1.5 hours and Lexia studied for 97 minutes. How many minutes more did Kwame and Connor study than Lexia?
Answer with step-by-step thinking: Kwame = 2.5 hours * 60 minutes = 150 minutes. Connor = 1.5 hours * 60 minutes = 90 minutes. Kwame + Connor = 150 + 90 = 240 minutes. 240 - 97 = 143 minutes. Kwame and Conner studied 143 minutes more than Lexia.
So the answer is 143.


Question: Rory has 30 more jellybeans than her sister Gigi who has 15 jellybeans. Lorelai has already eaten three times the number of jellybeans that both girls have. How many jellybeans has Lorelai eaten?
Answer with step-by-step thinking:
Rory has 30 more jellybeans than Gigi who has 15 so Rory has 30 + 15 = 45 jellybeans. Rory has 45 jellybeans and Gigi has 15 so that's 45 + 15 = 60 jellybeans total. Lorelai has eaten three times the amount of jellybeans that both girls have so she has eaten 3 * 60 = 180 jellybeans.
So the answer is 180.
