Question: Remi wants to drink more water. He has a refillable water bottle that holds 20 ounces of water. That week Remi refills the bottle 3 times a day and drinks the whole bottle each time except for twice when he accidentally spills 5 ounces the first time and 8 ounces the second time. In 7 days how many ounces of water does Remi drink?
Answer: Remi drinks the same amount of water every day for a week except for when he spills some of it. His water bottle holds 20 ounces which he drinks 3 times a day, 20 x 3 = 60 ounces a typical day. Over 7 days, without spilling anything, Remi drinks 60 ounces x 7 days = 420 ounces. Except Remi spills 8 + 5 ounces of water during the week = 13 ounces of water Remi spills. Total, Remi drinks 420 ounces - 13 ounces of spilled water = 407 ounces Remi drank during the week. The answer is 407.

Question: With 40 seconds left to play in the basketball game, the Dunkinville Hornets were leading the Fredingo Fireflies by a score of 86 to 74. In the remaining seconds in the game, the Fireflies scored 7 three-point baskets while holding the Hornets to only 2 two-point baskets to win the game. How many more points did the Fireflies score in the game than did the Hornets?
Answer:
In the final 40 seconds, the Fireflies scored seven 3 - point baskets to improve their score by 3 * 7 = 21 points. Thus, the Fireflies final total was 74 + 21 = 95 points. In the final 40 seconds, the hornets scored an additional two 2 - point baskets to improve their score by 2 * 2 = 4 points. Thus, the Hornets final total was 86 + 4 = 90 points. The final difference in points between the two teams was 95 - 90 = 5 points. The answer is 5.
