Question: Jackson is laying tile in a courtyard that measures 10 feet by 25 feet. He needs 4 tiles per square foot of space. 40% of the tiles are green marble that costs $3/tile, and the rest are red tile that costs $1.50/tile. How much does he pay total for tile?
Answer: Step-by-step reasoning process: First find the area of the courtyard: 10 feet * 25 feet = 250 feet. Then multiply the area by the number of tiles per square foot to find the total number of tiles needed: 250 feet * 4 tiles / square foot = 1000 tiles. Then multiply the number of tiles by the percentage that are green to find the total number of green tiles: 1000 tiles * 40% = 400 tiles. Subtract that number from the total number of tiles to find the number of red tiles: 1000 tiles - 400 tiles = 600 tiles. Multiply the number of red tiles by the price per red tile to find the cost of the red tiles: 600 tiles * $1.50 / tile = $900. Multiply the number of green tiles by the price per green tile to find the cost of the green tiles: 400 tiles * $3.00 / tile = $1200. Then add the cost of each type of tile to find the total cost: $900 + $1200 = $2100.
So the answer is 2100.

Question: Michelle uses 40 beads in making a necklace. She uses 5 blue beads and 2 times as many red beads as blue beads. Then she uses the same number of white beads as the blue and red beads combined. If the rest of the beads she uses are silver, how many silver beads does she use?
Answer: Step-by-step reasoning process: Michelle uses 5 x 2 = 10 red beads. She uses 5 + 10 = 15 white beads. So she uses a total of 5 + 10 + 15 = 30 blue, red, and white beads. Therefore, she uses 40 - 30 = 10 silver beads.
So the answer is 10.

Step-by-step reasoning process: Flora has 50 * 2 = 100 books. Gary has 50 / 2 = 25 books. Together they own 100 + 25 + 50 = 175 books.
So the answer is 175.
