Reasoning and answer: The first round will result in 1000 * 10% = 100 employee layoffs. There are 1000 - 100 = 900 employees remaining. The second round will result in 900 * 10% = 90 employee layoffs. There are 900 - 90 = 810 employees remaining. The third round will result in 810 * 10% = 81 employee layoffs. The total number of of employees laid off is 100 + 90 + 81 = 271.
The answer: 271

Reasoning and answer: First, if the a full tire needs 500 cubic inches of air, then two empty tires need: 500 cubic inches / tire * 2 tires = 1000 cubic inches. Accordingly, the 40% - full tire needs 500 cubic inches * (100% - 40%). So, we find the 40% - full tire needs 500 cubic inches * (60%) = 300 cubic inches. And, the 70% - full tire needs 500 cubic inches * (100% - 70%). So, the 70% - full tire needs 500 cubic inches * (30%) = 150 cubic inches. Now add up the needs of all the tires to find the total number of cubic inches needed: 1000 cubic inches + 300 cubic inches + 150 cubic inches = 1450 cubic inches. Finally, if the pumps each hold 50 cubic inches, the total number of pumps needed is 1550 cubic inches / 50 cubic inches / pump = 29 pumps.
The answer: 29

Question: Carson is refilling his tires. Each tire can hold 500 cubic inches of air. Two of the tires are completely flat and empty. One tire is 40% full and the last tire is 70% full. If Carson injects 50 cubic inches of air with each pump, how many pumps will it take him to fill all the tires?

Reasoning and answer: The store received 20 / 2 = 10 pallets of paper towels. They received 20 / 4 = 5 pallets of tissues. They received 20 / 5 = 4 pallets of paper plates. Thus, the store received 20 - 10 - 5 - 4 = 1 pallet of paper cups.
The answer: 1
