Q: Aryan owes Fernanda $1200, which is twice what Kyro owes Fernanda. Aryan decides to pay 60% of her debt to Fernanda, and Kyro pays Fernanda 80% of her dept. If Fernanda had $300 in her savings account and adds the money she's been paid by her debtors to the savings account, calculate the total amount of money in her savings account now.
A: Kyro owes Fernanda half of what Aryan owes Fernanda, a total of 1 / 2 * $1200 = $600. Aryan pays 60% of her dept, which equals 60 / 100 * 1200 = $720. If Fernanda adds the amount she's been paid by Aryan to her savings account, it increases to $300 + $720 = $1020. Kyro also pays her debt by 80 / 100 * $600 = $480. When Fernanda adds the amount she's been paid by Kyro to her savings account, the total amount of money in the savings account increases to $1020 + $480 = $1500. The answer is 1500.
Question: Selina is selling some of her old clothes to a second-hand store. They will buy her pants for $5 each, her shorts for $3 each, and her shirts for $4 each. She sells 3 pairs of pants, 5 pairs of shorts, and some shirts. After she gets her money, she sees 2 shirts that she likes which cost $10 each and buys them. She leaves the store with $30. How many shirts did she sell to the store?
Answer:
The shirts she bought cost her $20 because 2 x 10 = 20. She earned $50 selling her clothes because 20 + 30 = 50. She made $15 off pants because 3 x 5 = 15. She made 15 dollars from shorts because 3 x 5 = 15. She made $20 off shirts because 50 - 15 - 15 = 20. She sold 5 shirts because 20 / 4 = 5. The answer is 5.
