Q: Juanita goes through 1 bottle of sunscreen a month. She likes to stock up for the entire year when a certain website offers 30% off her entire purchase. If each bottle is $30.00 how much will all of the sunscreen cost after the discount?
A: She goes through 1 bottle a month and she likes to stock up for the entire year, which is 12 months so she needs 1 * 12 = 12 bottles. Each bottle is $30.00 and she needs 12 bottles so they will cost 30 * 12 = $360.00. The website offers a 30% discount off of her $360.00 purchase so the discount will be .30 * 360 = $108.00. Her sunscreen costs $360.00 and her discount is 108.00 making her purchase total 360 - 108 = $252.00. The answer is 252.
Question: Samanta is planning a party for her friend Marta. She decided to raise some money among the guests she invited, to buy Marta a gift. Every participant gave Samanta $5 for this purpose and she herself put in $10. The gift cost was lower than expected, so there was $15 leftover. What was the price of the gift, if there were 12 guests invited?
Answer: From all the guests Samanta got $5 / guest * 12 guests = $60. Including money Samanta put herself, she had $60 + $10 = $70. The cost of the gift was $70 - $15 = $55. The answer is 55.
[Question]Karen's class fund contains only $10 and $20 bills, which amount to $120. The number of $10 bills is twice as many $20 bills. How many $20 bills do they have in their fund?
[Answer]If n is the number of $20 bills then 2n is the number of $10 bills. So the equation will be $10(2n) + $20n = $120. By combining like terms, the equation becomes 40n = 120. So, the value of n which represents the number of $20 bills is 120 / 40 = 3. The answer is 3.

Question: John buys 500 newspapers. Each newspaper sells for $2. He sells 80% of them. He buys them all for 75% less than the price at which he sells them. How much profit does he make?
Answer:
He sells 500 * .8 = 400 newspapers. He sells them for 400 * 2 = $800. He gets a discount of 2 * .75 = $1.5 on the newspapers. So he buys them for 2 - 1.5 = $.5. So he spent 500 * .5 = $250 buying them. That means he made a profit of 800 - 250 = $550. The answer is 550.
