Question: Carla is making smoothies. If she uses 500 ml of watermelon puree and 100 ml of cream, how many 150 ml servings can she make?
Answer: Step-by-step reasoning process: First find the total volume of the smoothie mix: 500 ml + 100 ml = 600 ml. Then divide the total volume by the volume per serving to find the number of servings: 600 ml / 150 ml / serving = 4 servings.
So the answer is 4.

Question: Ronnie is a train engineer. His train pulls 3 red boxcars, 4 blue boxcars, and 7 black boxcars. If the black boxcars can each hold 4000 pounds of coal, which is half as much as what the blue boxcars can hold, and the red boxcars can hold 3 times as much as the blue boxcars, how many pounds of coal can all of the train's boxcars combined hold?
Answer: Step-by-step reasoning process: If we let X represent the number of pounds of coal that the blue boxcar can hold, then 4000 = (1 / 2)X. Solving for X, we get X = 8000 pounds of coal, which represents what the blue car can hold. Thus, the red boxcar can hold 3 * 8000 = 24,000 pounds of coal. 3 red boxcars can carry 3 * 24,000 = 72,000 pounds of coal. 7 black boxcars can carry 7 * 4,000 = 28,000 pounds of coal. 4 blue boxcars carry 4 * 8,000 = 32,000 pounds of coal. Together, all the trains boxcars can carry 72,000 + 28,000 + 32,000 = 132,000 pounds of coal.
So the answer is 132000.

Question: A frog lays 800 eggs a year. 10 percent dry up, and 70 percent are eaten. 1/4 of the remaining eggs end up hatching, how many frogs hatch out of the 800?
Answer: Step-by-step reasoning process: Dried up:800(.10) = 80 eggs. 800(.70) = 560 eggs. Total left:800 - 80 - 560 = 160 eggs. 160 / 4 = 40 eggs survive to hatch.
So the answer is 40.

Question: Hansel makes $30,000 a year and just received a 10% raise. Gretel makes the same amount as Hansel but received a 15% raise. How much more money will Gretel make compared to Hansel?
Answer:
Step-by-step reasoning process: Hansel makes $30,000 and received a 10% raise so his raise is 30,000 * .10 = $3,000.00. Hansel now makes 30,000 + 3,000 = $33,000 a year. Gretel makes $30,000 and received a 15% raise so her raise is 30,000 * .15 = $4,500.00. Gretel now makes 30,000 + 4,500 = $34,500 a year. If Gretel makes $34,500 a year and Hansel makes $33,000 then Gretel makes 34,500 - 33,000 = $1,500 more a year than Hansel.
So the answer is 1500.
