Q: Bea and Dawn both have a lemonade stand. Bea sells her lemonade at 25 cents while Dawn sells hers at 28 cents. If Bea sold 10 glasses and Dawn sold 8 glasses, how much more money (in cents) did Bea earn than Dawn?
A: Bea's sales amount to $0.25 / glass x 10 glasses = 250 cents. Dawn's sales amount to $0.28 / glass x 8 glasses = 224 cents. So, Bea earned $2.50 - $2.24 = 26 cents more than Dawn. The answer is 26.
Question: Matt did his homework for 150 minutes. He spent 30% of that time on math and 40% on science. He spent the remaining time on other subjects. How much time did Matt spend on homework in other subjects?
Answer: Matt spent on math and science 30% + 40% = 70% of the time. This means he did homework from these two subjects for 70 / 100 * 150 minutes = 105 minutes. So Matt spent 150 minutes - 105 minutes = 45 minutes doing homework from other subjects. The answer is 45.
[Question]Kevin repairs phones at his job. At the beginning of the day, Kevin has 15 phones that need to be repaired. By the afternoon, Kevin has successfully repaired 3 of the 15 phones and a client has dropped off 6 more phones that need fixing. If a coworker of Kevin's offers to help him and fix half of the damaged phones, how many phones will each person need to repair?
[Answer]Kevin begins the day with 15 phones and repairs 3 by the afternoon, so Kevin still has to repair 15 - 3 = 12 phones. A client drops off 6 additional phones that require fixing, increasing the total to 12 + 6 = 18 phones. If Kevin's coworker helps Kevin fix half of the phones, then each person needs to fix 18 / 2 = 9 phones. The answer is 9.
Q: Chris wants to hold his breath underwater for 90 straight seconds so he starts training each day. On the first day, he holds it for 10 seconds. On the second day, he holds it for 20 seconds. On the third day, he holds it for 30 seconds. After realizing that he can hold it for ten extra seconds each day, he realizes he can calculate how many days it is until he reaches 90 if he keeps up the same pace. So how many days until he can hold his breath for 90 seconds?
A: He still has to improve by 60 more seconds because 90 - 30 = 60. This will take 6 days because 60 / 10 = 6. The answer is 6.
Question: Brandon has a collection of 20 baseball cards. Malcom has 8 more cards than Brandon. However, then Malcom gives half of his cards to his friend Mark. How many cards does Malcom have left?
