John injures his shoulder while lifting weights. After the injury, his bench press goes down 80%. After a bit of training, he manages to triple the weight he can bench. If he started with a 500-pound bench press, what is it now? Give the rationale and then the answer.
Let's think step by step. He lost 500 * .8 = 400 pounds from his bench. So his bench went to 500 - 400 = 100 pounds. After training it increased to 100 * 3 = 300 pounds.. The answer is: 300.

There are six unicorns in the Enchanted Forest. Everywhere a unicorn steps, four flowers spring into bloom. The six unicorns are going to walk all the way across the forest side-by-side, a journey of 9 kilometers. If each unicorn moves 3 meters forward with each step, how many flowers bloom because of this trip? Give the rationale and then the answer.
Let's think step by step. First convert the total length of the journey from kilometers to meters: 9 kilometers * 1000 meters / kilometer = 9000 meters. Then divide this by the length of one step to find the number of steps in the journey: 9000 meters / 3 meters / step = 3000 steps. Then multiply the number of steps by the number of flowers per step to find how many flowers one unicorn creates on the journey: 3000 steps * 4 flowers / step = 12000 flowers. Then multiply the number of flowers per unicorn by the number of unicorns to find the total number of flowers created: 12000 flowers / unicorn * 6 unicorns = 72,000 flowers.. The answer is: 72000.

On each of 7 Mondays, it rained 1.5 centimeters. On each of 9 Tuesdays it rained 2.5 centimeters. How many more centimeters did it rain on Tuesdays than Mondays? Give the rationale and then the answer.
Let's think step by step. Mondays: 7 * 1.5 = 10.5. Tuesdays: 9 * 2.5 = 22.5. 22.5 - 10.5 = 12 cm. It rained 12 centimeters more on Tuesdays than on Mondays.. The answer is: 12.
