Question: In a national park, the number of redwoods is 20% more than the number of pines. If there are 600 pines in the national park, calculate the total number of pines and redwoods that are there.
Answer with step-by-step thinking: If there are 600 pines, there are 20 / 100 * 600 = 120 more redwoods than pine trees in the national park. In total, there are 120 + 600 = 720 redwoods in the national park. Altogether, there are 720 + 600 = 1320 pines and redwoods in the national park.
So the answer is 1320.

Question: Mrs. Lim milks her cows twice a day. Yesterday morning, she got 68 gallons of milk and in the evening, she got 82 gallons. This morning, she got 18 gallons fewer than she had yesterday morning. After selling some gallons of milk in the afternoon, Mrs. Lim has only 24 gallons left. How much was her revenue for the milk if each gallon costs $3.50?
Answer with step-by-step thinking: Mrs. Lim got 68 gallons - 18 gallons = 50 gallons this morning. So she was able to get a total of 68 gallons + 82 gallons + 50 gallons = 200 gallons. She was able to sell 200 gallons - 24 gallons = 176 gallons. Thus, her total revenue for the milk is $3.50 / gallon x 176 gallons = $616.
So the answer is 616.

Question: Tony is driving his car between his town and a friend's down. The towns are 120 miles apart and he gets there in 3 hours. The next day, he is driving to see another friend who lives 200 miles away from his friend. If he drives at the same speed, how long will the drive take?
Answer with step-by-step thinking:
He is driving 40 MPH because 120 / 3 = 40. It will take him 5 hours because 200 / 40 = 5.
So the answer is 5.
