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 with step-by-step thinking: 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.
So the answer is 768.

Question: Five dozens of people are attending your family reunion. Your family was assigned to bring the cans of soda. Each box of soda contains 10 cans and costs $2 per box. It was assumed that each person can consume 2 cans of soda. If you are six in the family and agreed to pay equally for the cost, how much will each of your family members pay?
Answer with step-by-step thinking: Five dozens of people is equal to 5 x 12 = 60. 60 x 2 = 120 cans of soda are needed. So, this means 120 / 10 = 12 boxes of soda must be purchased. Thus, it will amount to $2 x 12 = $24. Therefore, each family member will pay $24 / 6 = $4.
So the answer is 4.

Question: Johns goes to the gym 3 times a week. He spends 1 hour each day lifting weight. Additionally, he also spends a third of his weightlifting time warming up and doing cardio each day. How many hours does he spend at the gym a week?
Answer with step-by-step thinking:
He spends 60 / 3 = 20 minutes warming up. So he spends 60 + 20 = 80 minutes at the gym per day. That means he spends 80 * 3 = 240 minutes at the gym. So he spends 240 / 60 = 4 hours at the gym a week.
So the answer is 4.
