The school decided to have a fundraiser to collect $750 for new basketball equipment. Families could donate $25, $50, or $100. Families who donated $25 got Bronze Status. Families who donated $50 got Silver Status. Families who donated $100 got Gold Status. With one day left in the fundraiser, the school has 10 Bronze Status families, 7 Silver Status Families and 1 Gold Status family. How much do they need to raise on the final day to reach their goal? Give the rationale and then the answer.
Let's think step by step. They collected $250 from Bronze Status families because 10 times 25 equals 250. They collected $350 from Silver Status families because 7 times 50 equals 350. They collected $100 from Gold Status families because 1 times 100 equals 100. Therefore, they collected $700 thus far because 250 plus 350 plus 100 equals 700. They need to collect $50 more because 750 minus 700 equals 50.. The answer is: 50.

Stacy just bought a 6 month prescription of flea & tick medicine for her dog for $150.00 online. Her cashback app was offering 10% cashback and she has a mail-in rebate for $25.00 on a 6-month prescription. How much will the medicine cost after cash back and rebate offers? Give the rationale and then the answer.
Let's think step by step. Her cash back app gave her 10% back on $150.00 so that's .10 * 150 = $15.00 cash back. She received $15.00 from the cashback app and has a $25.00 mail - in rebate for a total of 15 + 25 = $40.00 discounts. She spent $150.00 for the medicine and has $40.00 worth of discounts so the medicine will cost 150 - 40 = $110.00.. The answer is: 110.

Joseph had socks of many different colors. His dresser drawer was filled to overflowing with red, blue, black, and white socks. Uncertain of how many pairs he had of each color, he began to sort his socks. He discovered that he had three more pairs of blue socks than he had pairs of black socks. He had one less pair of red socks than he had pairs of white socks. He had twice as many blue socks as he had of red socks. And he counted a total of 6 red socks. What is the total number of Joseph's socks? Give the rationale and then the answer.
Let's think step by step. Starting with 6 red socks, twice the number of blue socks as red meant Joseph had 2 * 6 = 12 blue socks. With one less pair of red socks than white socks, this meant 2 fewer red socks than white, for a total of 6 - 2 = 4 white socks. Also, 12 blue socks = 6 pairs of blue socks. With three more pairs of blue socks than pairs of black socks, this means he had 6 - 3 = 3 pairs of black socks. And three pairs of black socks corresponds to 3 * 2 = 6 black socks. Thus, in total, he had 6 + 12 + 4 + 6 = 28 socks.. The answer is: 28.
