[Question]To produce one chocolate bar, a company needs 1.5 grams of sugar. Every minute the company produces 36 chocolate bars. How many grams of sugar will the company use in two minutes?
[Answer]In one minute the company produces 36 chocolate bars, which means they use 36 * 1.5 = 54 grams of sugar. So in two minutes, the company uses 54 * 2 = 108 grams of sugar to produce chocolate bars. The answer is 108.

[Question]Darrel has 76 quarters, 85 dimes, 20 nickels and 150 pennies. If he drops all of his money into a coin-counting machine, they will convert his change into dollars for a 10% fee. How much will he receive after the 10% fee?
[Answer]He has 76 quarters so that's 76 * .25 = $19.00. He has 85 dimes so that's 85 * .10 = $8.50. He has 20 nickels so that's 20 * .05 = $1.00. He has 150 pennies so that's 150 * .01 = $1.50. All total he has 19 + 8.5 + 1 + 1.5 = $30.00. They charge a 10% fee to count and convert his change into dollars so they will charge him .10 * 30 = $3.00. He had $30.00 and they charged him $3.00 in fees so he now has 30 - 3 = $27.00. The answer is 27.

[Question]Toby, the Alaskan Malamute, can pull a sled at a speed of 20 miles per hour if the sled is unloaded, but he pulls the same sled at a speed of 10 miles per hour if the sled is fully loaded. If Toby takes a continuous 4-part journey, first pulling the loaded sled for 180 miles, then pulling the unloaded sled for 120 miles, then pulling the loaded sled 80 miles, and finally, pulling the unloaded sled another 140 miles, how many hours in total will Toby spend pulling the sled?
[Answer]
Pulling a loaded sled at 10 mph for 180 miles takes 180 / 10 = 18 hours. Pulling an unloaded sled at 20 mph for 120 miles takes 120 / 20 = 6 hours. Pulling a loaded sled at 10 mph for 80 miles takes 80 / 10 = 8 hours. Pulling an unloaded sled at 20 mph for 140 miles takes 140 / 20 = 7 hours. In total, Toby will have pulled the sled for 18 + 6 + 8 + 7 = 39 hours. The answer is 39.
