[Answer]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. The answer is 143.
Q: A retailer sells any shirt for the same price and any pair of pants for the same price, but the price of shirts and pants are not the same. Say you bought 2 shirts and 3 pairs of pants for $120 in total, then you realized you didn't need the extra pants. What's the price of 1 shirt at this place if when you returned all 3 pairs of pants you were refunded 25% of what you originally paid?
A: If I paid $120 and I was refunded 25% for all the 3 pants, then that means I received 25% * 120 = $30. This means the total price of the 2 shirts was 120 - 30 = 90. The price of one shirt is thus 90 / 2 = 45. The answer is 45.
Question: Kylie and Kayla pick apples together and take home 340 apples total. If Kayla picked 10 more than 4 times the amount of apples that Kylie picked, how many apples did Kayla pick?
Answer: Let x be the number of apples Kylie picked. Kayla picked 10 + 4x apples. 340 = x + (10 + 4x). 340 = 5x + 10. 330 = 5x. x = 66 apples. Kayla picked 10 + 4(66) = 274 apples. The answer is 274.
[Question]One of the activities in Grade 6 PE class is to get the average weight of the students from each group. In one of the groups, the average weight of five girls is 45 kg while the average weight of five boys is 55 kg. What is the average weight of the ten students from that group?
[Answer]The sum of the weights of the five girls is 45 kg x 5 = 225 kg. The sum of the weights of the five boys is 55 kg x 5 = 275 kg. The sum of the weights of the ten students is 225 kg + 275 kg = 500 kg. Hence, the average weight of those ten students is 500 kg / 10 = 50 kg. The answer is 50.
Q: There are 20 hands in Peter's class, not including his. Assume every student in the class has 2 arms and 2 hands. How many students are in Peter's class including him?

Question: If Brooke adds eight balloons to his current 12, and Tracy adds 24 to her current 6, how many balloons will they have in total if Tracy pops half of her balloons?
Answer:
When Brooke gets twelve more balloons, his total becomes 12 + 8 = 20. When Tracy adds 24 more balloons to her 6, her total number of balloons becomes 24 + 6 = 30. When half of Tracy's balloons pop, she remains with 1 / 2 * 30 = 15. The combined total balloons for the two is 15 + 20 = 35 balloons. The answer is 35.
