Answer the following question.
Madison and Gigi have to run a total of 2400 meters in gym class. The track is 150 meters around. If they each have run 6 laps, how many more laps do they have to run before they reach 2400 meters?
Step-by-step reasoning process: The have run 12 laps because 6 + 6 = 12. They have run 1,800 meters because 12 x 150 = 1,800. They have 600 more meters to run because 2,400 - 1,800 = 600. The have to run 4 more laps because 600 / 150 = 4.
The answer is 4.

Answer the following question.
Katy makes some brownies to eat throughout the week. She eats 5 on Monday and twice as many on Tuesday. After she has eaten the brownies on Tuesday, all of the brownies she made are gone. How many brownies did Katy make?
Step-by-step reasoning process: On Tuesday, Katy ate 5 brownies * 2 = 10 brownies. As she has eaten all of the brownies she made, she must have made 5 Monday brownies + 10 Tuesday brownies = 15 brownies.
The answer is 15.

Answer the following question.
A TV show costs $100,000 per episode for the first season and twice that much for every other season. The first season had 12 episodes, and every season after that had 50% more episodes except the last season, which had 24 episodes. The show had 5 seasons. How much did it cost to produce all the episodes?
Step-by-step reasoning process: The first season cost 12 * 100,000 = $1,200,000. Season 2 - 4 had 12 * .5 = 6 more episodes per season than the first. So they each had 12 + 6 = 18 episodes. That means there were 18 * 3 + 24 = 78 episodes in the last 4 seasons. So those episodes cost 2 * 100,000 = $200,000. For a total cost of 200,000 * 78 = $15,600,000. So the total cost was 15,600,000 + 1,200,000 = $16,800,000.
The answer is 16800000.

Answer the following question.
There are 25 different layers of rock in a canyon’s strata. Five of the layers are limestone. Half of the rest are sandstone. Four of the remaining are quartz. Half of the rest are shale. The rest are all different kinds of rock. How many kinds of rock make up only one layer in the canyon’s strata?
Step-by-step reasoning process: There are 25 - 5 = 20 layers of rock that are not limestone. Half of those 20 are sandstone, so there are 20 / 2 = 10 that are not limestone or sandstone. Four of those are quartz, so 10 - 4 = 6 layers are not limestone, sandstone, or quartz. Half of the rest are shale, so 6 / 2 = 3 kinds of rock remain that make up only one layer in the strata.
The answer is 3.
