Reasoning and answer: If the price of a lawnmower was $1800 a year ago, 2 / 5 less than the cost right now, then it now costs 2 / 5 * 1800 = $720 more to buy one lawnmower. The total cost of buying one lawnmower right now is $1800 + $720 = $2520. To purchase 4 such lawnmowers, Mr. Lucian will have to pay $2520 * 4 = $10080.
The answer: 10080

Question: A year ago, the total cost of buying a lawnmower was 2/5 times less than the cost it goes for now. If the cost was $1800 a year ago, calculate how much it would cost Mr. Lucian to buy 4 such lawnmowers.


First find the total number of pieces of candy Anna gets: 14 pieces / house * 60 houses = 840 pieces. Then find the total number of pieces of candy Billy gets: 11 pieces / house * 75 houses = 825 pieces. Then subtract the number of pieces Billy gets from the number Anna gets to find the difference: 840 pieces - 825 pieces = 15 pieces.
The answer: 15
Reverse engineering the question: Anna goes trick-or-treating in a subdivision where she gets 14 pieces of candy per house. Her brother Billy goes trick-or-tricking in a neighboring subdivision where he gets 11 pieces of candy per house. If the first subdivision has 60 houses and the second subdivision has 75 houses, how many more pieces of candy does Anna get?


Reasoning and answer: The number of guests that bring a plus one is 30 / 2 = 15 guests. The total number of guests at the party, including the plus ones, is 30 + 15 = 45 guests. Since there are 3 courses, Wickham will need 45 * 3 = 135 plates.
The answer: 135

Question: Wickham is throwing a huge Christmas party. He invites 30 people. Everyone attends the party, and half of the guests bring a plus one (one other person). He plans to serve a 3-course meal for the guests. If he uses a new plate for every course, how many plates does he need in total for his guests?


The block has 16 servings and he has eaten 5 servings leaving 16 - 5 = 11 servings of cheese. There are 11 servings of cheese left and each serving is 110 calories for a total of 11 * 110 = 1,210 calories.
The answer: 1210
Reverse engineering the question: There are 110 calories in a serving of cheese. Rick buys the large blocks that have 16 servings per block. If Rick has already eaten 5 servings of cheese, how many calories are remaining in the block?


Reasoning and answer: First find the total number of ounces in the water cooler: 3 gallons * 128 ounces / gallon = 384 ounces. Then find the total number of dixie cups Bill pours: 5 rows * 10 chairs / row = 50 chairs. Then find the total number ounces Bill pours: 50 attendees * 6 ounces / attendee = 300 ounces. Then subtract the amount of water Bill pours from the cooler from the initial amount to find the final amount: 384 ounces - 300 ounces = 84 ounces.
The answer: 84

Question: While preparing for a meeting, Bill fills Dixie cups with water from out of a water cooler. The water cooler initially contains 3 gallons of water, and each Dixie cup holds 6 ounces of water. If Bill fills one cup of water per each meeting chair, and there are 5 rows of meeting chairs with 10 chairs in each row, then how many ounces of water will be left in the cooler after all cups have been are filled? (There are 128 ounces in a gallon.)


Reasoning and answer: Roque takes 2 * 3 = 6 hours a week to walk to work. Roque takes 6 * 2 = 12 hours a week to walk to and from work. Roque takes 1 * 2 = 2 hours a week to bike to work. Roque takes 2 * 2 = 4 hours a week to bike to and from work. In total, Roque takes 12 + 4 = 16 hour a week to go to and from work.
The answer: 16

Question:
It takes Roque two hours to walk to work and one hour to ride his bike to work. Roque walks to and from work three times a week and rides his bike to and from work twice a week. How many hours in total does he take to get to and from work a week with walking and biking?
