Q: Earl has $90; Fred has $48; Greg has $36. Earl owes Fred $28. Fred owes Greg $32. Greg owes Earl $40. When all debts are paid, how much will Greg and Earl have together in dollars?
A: Earl will have $90 - $28 = $62 after paying off his debt to Fred. Fred will have $48 + $28 = $76 after being paid by Earl. But then Fred will have $76 - $32 = $44 after paying Greg. Greg will have $36 + $32 = $68 after Fred paid him. Then, Greg will have $68 - $40 = $28 after paying off his debt to Earl. Then, Earl will then have $62 + $40 = $102. So together, Greg and Earl will have $28 + $102 = $130. The answer is 130.
Question: Lucy lost one-third of her money. She then spent one-fourth of the remainder, and only left with $15. How much money did Lucy have at the beginning?
Answer: The $15 is 1 - 1 / 4 = 3 / 4 of the money left. Since 3 / 4 is equal to $15, then 1 / 4 is equal to $15 / 3 = $5. So Lucy had $5 x 4 = $20 left after losing 1 / 3 of her money. Hence, $20 is 1 - 1 / 3 = 2 / 3 of the money that Lucy had at the beginning. Since 2 / 3 is equal to $20, then 1 / 3 is equal to $20 / 2 = $10. Therefore, Lucy had $10 x 3 = $30 at the beginning. The answer is 30.
[Question]Adam earns $40 daily in his job. 10% of his money is deducted as taxes. How much money will Adam have earned after taxes after 30 days of work?
[Answer]The amount of money deducted from Adam's daily pay is $40 / 10 = $4. So after deducting 10%, Adam’s daily pay is $40 – $4 = $36. This means that in 30 days he earns $36 * 30 = $1080. The answer is 1080.
Q: Bailey needs to buy 2 new sets of towels for the guest bathroom and 4 new sets for her master bathroom. The set of towels for the guest bathroom are $40.00 each and the master bathroom set is $50.00 each. The store is currently offering 20% off so how much will Bailey spend on towel sets?
A: She needs 2 sets of guest towels that are $40.00 each so that’s 2 * 40 = $80.00. She needs 4 sets of master bath towels that are $50.00 each so that’s 4 * 50 = $200.00. Together, the towels will cost 80 + 200 = $280.00. The store is offering 20% off of her $280.00 towels so that’s 280 * .20 = $56.00 discount. Her $280.00 towels have a $56.00 discount making them 280 - 56 = $224.00. The answer is 224.
