Question: Yves and his siblings ordered pizza and asked to have it cut into 16 slices. During dinner time, they only ate one-fourth of it. The next day, Yves ate one-fourth of the remaining pizza. Then his two siblings ate 2 slices each. How many slices of pizza were left?
Answer: During dinner time, Yves and his siblings ate 16 / 4 = 4 slices. So the next day, there were still 16 - 4 = 12 slices left. The next day, Yves ate 12 / 4 = 3 slices of pizza. Thus, there were 12 - 3 = 9 slices left. Then, his two siblings ate 2 x 2 = 4 slices of pizza. Therefore, there were still 9 - 4 = 5 slices of pizza left. The answer is 5.
[Question]Simon collected treasures on the beach during his summer vacation. He collected a bucket of pearly seashells, a jar full of smooth sea glass, and a bag of ten sand dollars. If the jar holds three times as many pieces of glass as the bag does sand dollars, and the bucket holds five times as many seashells as the jar holds pieces of glass, how many treasures did Simon find on the beach?
[Answer]The jar holds 3 * 10 = 30 pieces of glass. The bucket holds 5 * 30 = 150 seashells. Simon found 10 + 30 + 150 = 190 treasures on the beach. The answer is 190.
Q: Rob planned on spending three hours reading in preparation for his literature exam. If he ends up spending only three-quarters of this time reading, and he reads a page every fifteen minutes, how many pages did he read in this time?
A: 1 hour is 60 minutes so 3 hours is 3 * 60 = 180 minutes. Three - quarters of 180 minutes is (3 / 4) * 180 = 135 minutes. He spends 15 minutes on 1 page so he will spend 135 minutes on 135 / 15 = 9 pages. The answer is 9.
Question: Selene buys two instant cameras at $110 and three digital photo frames at $120 each. She gets a 5% discount on all the items she purchased. How much does she pay in all?
Answer:
Two instant camera cost 2 x $110 = $220. Three digital photo frames cost 3 x $120 = $360. Thus, the total amount is $220 + $360 = $580. So, Selena gets a discount of 5 / 100 x 580 = $29. Therefore, Selena pays a total of $580 - $29 = $551. The answer is 551.
