Q: A cobbler can mend 3 pairs of shoes in an hour. From Monday to Thursday, the cobbler works for 8 hours each day, and on Friday, he only works from 8am to 11am. How many pairs of shoes can the cobbler mend in a week?
A: 105
Step-by-step reasoning process: From Monday to Thursday, the cobbler can mend 3 x 8 = 24 pairs of shoes a day. From Monday to Thursday, he can mend 24 x 4 = 96 pairs of shoes. On Friday, he works for 11 - 8 = 3 hours. On Friday, he can mend 3 x 3 = 9 pairs of shoes. In a week, he can mend 96 + 9 = 105 pairs of shoes.


Q: A house’s living room, dining room and kitchen take up 1,000 sq ft. The house also has a guest bedroom and a master bedroom suite. If the guest bedroom is a quarter of the size of the master bedroom suite, and the house is 2,300 sq ft total, how large is the master bedroom suite?
A: 1040
Step-by-step reasoning process: The house is 2,300 sq ft and we know the non - bedroom sections take up 1,000 sq ft, so that leaves 2300 - 1000 = 1,300 sq ft for the bedrooms / bathrooms. Let x be the size of the master bedroom suite. Then the guest bedroom is 0.25x. So together the bedrooms are x + 0.25x = 1.25x in size. This means 1.25x = 1300. So x = 1300 / 1.25 = 1040 sq ft.


Q: Jackson wants to impress his girlfriend by filling her hot tub with champagne. The hot tub holds 40 gallons of liquid. Each bottle of champagne holds 1 quart. (There are 4 quarts per gallon). If each bottle of champagne costs $50, but Jackson gets a 20% volume discount, how much does he spend on champagne?
A: 6400
Step-by-step reasoning process: First find the number of quarts the hot tub holds by multiplying the number of gallons it holds by 4: 40 gallons * 4 quarts / gallon = 160 quarts. Then multiply the number of quarts of champagne Jackson buy by the normal price per bottle to find the cost before the discount: 160 quarts * $50 / quart = $8000. Then multiply that number by 20% to find the amount of the discount: $8000 * .2 = $1600. Finally, subtract the discount from the total cost to find the final amount Jackson pays: $8000 - $1600 = $6400.


Q: Chad sandwiches 2 crackers with a scoop of peanut butter. He has 5 of these crackers a night before bed. A box of crackers has 4 sleeves with each sleeve holding 28 crackers. How many nights will 5 boxes of crackers last him?
A: 56
Step-by-step reasoning process: Chad uses 2 crackers for each "sandwich" and has 5 sandwiches a night so he eats 2 * 5 = 10 crackers a night. The box has 4 sleeves of crackers and each sleeve has 28 crackers for a total of 4 * 28 = 112 crackers. 1 box has 112 crackers so 5 boxes will have 112 * 5 = 560 crackers. He eats 10 crackers a night and 5 boxes have 560 crackers so they will last him 560 / / 10 = 56 nights.
