[Question]John's new computer cost $1500. He needs to get a monitor and other peripherals that cost 1/5 that much. He also wants to upgrade the $300 video card in the base computer with one that costs twice as much. How much did he spend?
[Answer]The peripherals cost 1500 / 5 = $300. The video card cost 300 * 2 = $600. So it cost 600 - 300 = $300 more. That means the total cost was 1500 + 300 + 300 = $2100. The answer is 2100.
Q: Janet has 1/3 of a bottle of rose shampoo and 1/4 of a bottle of jasmine shampoo. If she uses 1/12 of a bottle of shampoo per day, how many days will her shampoo last?
A: First cross - multiply to give both fractions the same denominator, then add the fractions: 1 / 3 + 1 / 4 = 4 / 12 + 3 / 12. Then add these fractions to find that she has 4 / 12 + 3 / 12 = 7 / 12 of a bottle of shampoo left. Then divide the total amount of shampoo she has by the amount she uses per day to find the number of days the shampoo will last: 7 / 12 / 1 / 12 / day = 7 days. The answer is 7.
Question: A charity organization's goal is to distribute 400 boxes of food to a community that was recently destroyed by a flood. Each box contains $80 worth of food and $165 worth of additional supplies such as toiletries and fresh linens. Then, an anonymous donor gives the organization 4 times the amount of money they had already spent, allowing them to pack many more boxes. How many boxes do they pack in total?
Answer: Each box costs $80 + $165 = $245. They spent $245 / box x 400 boxes = $98,000 on 400 boxes. They were given another $98,000 x 4 = $392,000. They are able to pack another $392,000 / $245 / box = 1600 boxes. Altogether, they pack 1600 boxes + 400 boxes = 2000 boxes. The answer is 2000.
[Question]Aunt Gemma has four dogs. She feeds them with dog food twice a day. Each dog can consume 250 grams of food per meal. If aunt Gemma bought 2 sacks of dog food, each weighing 50 kilograms, how many days will those food last?
[Answer]Each dog consumes 250 grams x 2 = 500 grams of dog food each day. So, 4 dogs consume 500 grams x 4 = 2000 grams of dog food each day. Since there are 1000 grams in 1 kilogram, then the 4 dogs can consume 2000 / 1000 = 2 kilograms of dog food each day. Aunt Gemma bought a total of 50 kilograms x 2 = 100 kilograms of dog food. Hence, it will last 100 kilograms / 2 kilograms = 50 days. The answer is 50.
Q: Marcel goes to the store with Dale to buy groceries for cooking dinner. Marcel buys 10 ears of corn, and Dale buys half that amount. Dale buys 8 potatoes and Marcel buys some, too. If they check out together and end up buying 27 vegetables, how many potatoes did Marcel buy?
A: Marcel bought 10 ears of corn and Dale bought 1 / 2 what Marcel did, 10 x 1 / 2 = 10 / 2 = 5 ears of corn that Dale bought. Together, Marcel and Dale bought 10 + 5 = 15 ears of corn, or 15 vegetables. They end up buying 27 vegetables total, and from those 27, 15 of them were corn. The rest of the vegetables are potatoes, 27 vegetables - 15 ears of corn = 12 potatoes. Dale bought 8 potatoes, so Marcel bought 12 - 8 = 4 potatoes. The answer is 4.
Question: Mary and her two friends agreed to evenly pay for the cost of 2 pounds of chicken. Mary's mother went to the grocery and bought the 2-pound chicken, 3 pounds of beef that cost $4 per pound, and a liter of oil that costs $1. If Mary's mother paid a total of $16 for the grocery, how much should Mary and her two friends pay each for the chicken?
Answer:
Three pounds of beef cost $4 x 3 = $12. Mary's mother paid $12 + $1 = $13 for the beef and oil. Hence, the 2 - pound chicken cost $16 - $13 = $3. There are 1 (Mary) + 2 friends = 3 people who will split the $3 cost. Therefore, each of them will pay $3 / 3 = $1. The answer is 1.
