Question: Janet is considering two options to retile her bathroom. The turquoise tiles cost $13/tile and the purple tiles cost $11/tile. If Janet needs to tile two walls that measure 5 feet by 8 feet and 7 feet by 8 feet, and each square foot of wall takes 4 tiles, how much will Janet save by buying the purple tiles instead of the turquoise ones?
Answer: First find the area of the first wall: 5 feet * 8 feet = 40 square feet. Then find the area of the second wall: 7 feet * 8 feet = 56 square feet. Then add the areas of the two walls to find the total area: 40 square feet + 56 square feet = 96 square feet. Then divide the number of square feet by the number of tiles per square foot to find the total number of tiles needed: 96 square feet * 4 tiles / square foot = 384 tiles. Then find the difference in cost per tile: $13 / tile - $11 / tile = $2 / tile. Then multiply the number of tiles by the cost difference per tile to find the total cost difference: $2 / tile * 384 tiles = $768. The answer is 768.
[Question]Amy is collecting candy for the car pool. She has 5 chocolate bars, 7 times as many M&Ms as chocolate bars, and 6 times as many marshmallows as M&Ms. Amy then arranges the candies into baskets. If she fills each basket with 10 candies, how many baskets will Amy fill?
[Answer]Amy has 5 * 7 = 35 M&Ms. Amy has 35 * 6 = 210 marshmallows. Amy has 5 + 35 + 210 = 250 candies. She fills 250 / 10 = 25 baskets. The answer is 25.
Q: John has to replace the ball bearings for machines he works with. He has 10 machines and they take 30 ball bearings each. It normally costs $1 per ball bearing but right now there is a sale where they are only $.75. Also since he is buying in bulk he gets a further 20% discount. How much money did he save by buying them all during the sale rather than 1 at a time?
A: He needs to replace 30 * 10 = 300 ball bearings. The normal price is 300 * 1 = $300. Because of the sale he only has to pay 300 * .75 = $225. He then gets a discount which shaves another 225 * .2 = $45 off the price. That means he only pays 225 - 45 = $180. So he saved 300 - 180 = $120. The answer is 120.
Question: Ken, Dave, and Jerry played shuffleboard against one another while together vacationing in Florida. Ken won 5 more games than Dave, and Dave won 3 more games than Jerry. If Jerry won 7 games, what was the total number of games they played?
Answer: If Dave won 3 more games than Jerry, and Jerry won 7 games, then Dave won 10 games. If Ken won 5 more games than Dave, and Dave won 10 games, then Ken won 10 + 5 = 15 games. In total, the three friends played 7 + 10 + 15 = 32 games. The answer is 32.
