[Question]Ronald wants to make profits by re-selling some phones he bought a week ago. He bought 200 units for just $3000, and he wants to gain a third of the initial investment in profits when all units are sold. Including the profit margin, what will be the selling price for each phone?
[Answer]The profit Ronald wants is $3000 / 3 = $1000. The profit per phone sold will be $1000 / 200 phones = $5 / phone. The cost of each phone is $3000 / 200 phones = $15 / phone. The selling price including the profit will be $15 / phone + $5 / phone = $20. The answer is 20.
Q: Kaylin is five years younger than Sarah, who is twice as old as Eli, who is nine years older than Freyja. If Freyja is ten years old, how old is Kaylin?
A: Since Freyja is ten years old, Eli is 10 + 9 = 19 years old. Sarah's age is twice Eli's, then Sarah is 2 * 19 = 38 years old. Kaylin is five years younger than Sarah, then she is 38 - 5 = 33 years old. The answer is 33.
Question: Toby is counting goldfish in the local pond. He knows that only 25% of goldfish are at the surface and the rest are too deep below the surface to be able to see. If he counts 15 goldfish, how many are below the surface?
Answer: There are 60 goldfish because 15 / .25 = 60. 75% of the fish are below the surface because 100 - 25 = 75. There are 45 goldfish below the surface because 60 x .75 = 45. The answer is 45.
[Question]Kantana loves chocolate. Every Saturday she goes to the candy store and buys 2 chocolates for herself and 1 for her sister. This last Saturday she picked up an additional 10 chocolates as a birthday gift for her friend Charlie. How many chocolates did Kantana end up buying for the month?
[Answer]There is 1 Saturday in a week and there are 4 weeks in a month so there are 1 * 4 = 4 Saturdays in a month (on average). If Kantana buys herself 2 chocolates every Saturday then this means she buys 2 * 4 = 8 chocolates for herself for the month. Kantana also buys her sister 1 chocolate on these trips so she is picking up an additional 1 * 4 = 4 additional chocolates for her sister for the month. Kantana decided to also purchase some chocolates for her friend Charlie for his birthday. She bought Charlie 10 chocolates. This means that for the month she bought 10 chocolates for Charlie, 4 chocolates for her sister, and 8 chocolates for herself, 10 + 4 + 8 = 22 chocolates bought in total for the month. The answer is 22.

Question: Janet hires six employees. Four of them are warehouse workers who make $15/hour, and the other two are managers who make $20/hour. Janet has to pay 10% of her workers' salaries in FICA taxes. If everyone works 25 days a month and 8 hours a day, how much does Janet owe total for their wages and taxes for one month?
Answer:
First figure out how many hours each worker works per month by multiplying the number of days they work by the number of hours a day they work: 25 days * 8 hours / day = 200 hours. Then calculate how much one warehouse worker makes per month by multiplying their hourly rate by the number of hours they work: 200 hours * $15 / hour = $3000. Then multiply that number by 4 to find out how much all the warehouse workers make: $3000 / worker * 4 workers = $12,000. Now multiply the hours each manager works (also 200) by their hourly wage to find out how much one manager makes per month: 200 hours * $20 / hour = $4,000. Now multiply one manager's wages by the number of managers (2) to find their total wage amount: $4,000 / manager * 2 managers = $8,000. Now add the wages for the managers and the workers to find the total cost of the wages: $8,000 + $12,000 = $20,000. Now multiply the total wage bill by 10% to find how much the FICA taxes are: $20,000 * .1 = $2,000. Now add the total wage bill to the total tax amount to find the grand total: $2,000 + $20,000 = $22,000. The answer is 22000.
