[Question]Cupcakes are sold in packages of 10 and 15. Jean bought 4 packs of 15 cupcakes. If she will give one cupcake each to 100 children in the orphanage, how many packs of 10 cupcakes should she need to buy?
[Answer]Jean already bought 15 cupcakes x 4 packs = 60 cupcakes. She needs 100 - 60 = 40 more cupcakes. Thus, she needs to buy 40 / 10 = 4 packs of 10 cupcakes. The answer is 4.
Q: In a northwestern town, it rained 4 inches per day during the first 15 days of November. For the remainder of the month, the average daily rainfall was twice the amount observed during the first 15 days. What is the total amount of rainfall for this town in November, in inches?
A: Since November has 30 days, the town received 4 inches of rain for the first half of the month for 30 / 2 = 15 days. The total inches of rain that the town received for the 15 days is 15 * 4 = 60 inches. The rain falling in the town increased by 2 * 4 = 8 inches per day for the remaining half of the month. Therefore, for the rest of the month, the town received 8 * 15 = 120 inches of rain. The total amount of rain the town received in November is 120 + 60 = 180 inches. The answer is 180.
Question: In a big box, there are marbles in 4 colors. Inside, there are 20 red marbles. There are three times more green marbles than red. Yellow marbles make up 20% of the green marbles. How many marbles are of a different color if the total of all marbles in the box is three times more than the number of green marbles?
Answer: There are 3 * 20 = 60 green marbles. There are 60 * 20 / 100 = 12 yellow marbles. In total there are 3 * 60 = 180 marbles. That leaves 180 - 20 - 60 - 12 = 88 marbles of another color in the box. The answer is 88.
[Question]Melanie is making meatballs for dinner. The recipe calls for breadcrumbs. To make the breadcrumbs Melanie is going to tear 2 slices of bread into smaller pieces and then add them to a blender to grind them into fine crumbs. First she tears the bread slices each in half, then tears those halves in half. How many bread pieces is Melanie going to put into the blender?
[Answer]Melanie starts with 1 slice of bread that she tears in half, making 2 halves. She takes both of those halves and tears them each in half, 2 halves x 2 more halves in half = 4 pieces per slice of bread. Melanie is using 2 slices of bread x 4 pieces each = 8 pieces overall to add to the blender. The answer is 8.
Q: John buys 1/2 gallon jugs of cold brew coffee every 4 days. How many cups of coffee does he drink a day?
A: He drinks 128 / 2 = 64 ounces of coffee every 4 days. That means he drinks 64 / 4 = 16 ounces of coffee a day. So he drinks 16 / 8 = 2 cups a day. The answer is 2.
Question: Caleb and Cynthia are filling up their inflatable pool with water using buckets. They fill their buckets at the spigot and carry them to the pool. Caleb can add 7 gallons from his bucket and Cynthia can add 8 gallons from her bucket each trip. It will take 105 gallons to fill the pool. How many trips will it take for Caleb and Cynthia to fill the pool with their buckets?
Answer:
Each trip, they add Caleb's 7 gallons + Cynthia's 8 gallons = 15 gallons. Since they are adding 15 gallons every trip, to fill the 105 - gallon pool, it would take 105 / 15 = 7 trips. The answer is 7.
