Q: 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?
A: 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: Erica is getting dessert at a pie buffet where all the pies are the same size. She takes 1/5 of an apple pie and 3/4 of a cherry pie. What fraction of a whole pie did Erica take, expressed as a percentage?
Answer: First, find a common denominator for the fractions by multiplying 5 and 4: 5 * 4 = 20. Then convert 1 / 5 to twentieths by multiplying the top and bottom by 4: 1 / 5 * 4 / 4 = 4 / 20. Then convert 3 / 4 to twentieths by multiplying the top and bottom by 5: 3 / 4 * 5 / 5 = 15 / 20. Now that the two fractions have the same denominator, you can add them: 4 / 20 + 15 / 20 = 19 / 20. Now divide 19 by 20 and multiply the answer by 100 to convert the fraction to a percentage: 19 / 20 * 100 = %95. The answer is 95.
[Question]Micheal decided to take some piano lessons. One lesson costs $30 and lasts for 1.5 hours. How much will Micheal need to pay for 18 hours of lessons?
[Answer]One lesson lasts 1.5 hours, so 18 hours of them is 18 / 1.5 = 12 lessons. If one lesson costs $30, then 12 lessons cost 12 * 30 = $360. The answer is 360.
Q: James takes 5 oranges and breaks each orange into 8 pieces. He splits the pieces between 4 people. If an orange has 80 calories how many calories does each person get?
A: He makes 5 * 8 = 40 pieces. So each person gets 40 / 4 = 10 pieces. That means each person eats 10 / 8 = 1.25 of an orange. So each person eats 80 * 1.25 = 100 calories of orange. The answer is 100.
Question: Three blue chips are in a jar which is 10% of the entire chips. If 50% of the chips are white and the rest are green, how many green chips are there?
Answer: 10% + 50% = 60% of the chips in the jar are not green. So, 100% - 60% = 40% of the chips are green. There are 40% / 10% = 4 sets of 10% to make 40%. Hence, there are 3 chips x 4 sets = 12 green chips. The answer is 12.
Q: Aria has twice as many high school credits as Emily, who has twice the number of high school credits as Spencer. If Emily has 20 credits, what's twice the total number of high school credits the three have?
A:
If Emily has 20 credits, and Aria has 2 times as many, then Aria has 2 * 20 = 40 high school credits. Emily has twice the number of high school credits Spencer has, meaning Spencer has 20 / 2 = 10 high school credits. Altogether, the three have 40 + 20 + 10 = 70 high school credits. Twice the total number of high school credits the three have is 2 * 70 = 140. The answer is 140.
