Q: Mr. Maximilian is a dairy animal farmer and has 140 cows on his farm. Forty percent of the cows on his farm have a red spot, 25 percent of the cows without a red spot have a blue spot and the remaining cows do not have any spot. How many cows on the farm have no spot?
A: If Mr. Maximilian has 140 cows and 40% of them have red spots, then 40 / 100 * 140 = 56 cows have red spots. The number of cows with no red spot is 140 - 56 = 84 cows. Out of the 84 cows without a red spot, 25% of them have a blue spot, a total of 25 / 100 * 84 = 21 cows. The number of cows without any spot is 84 - 21 = 63 animals. The answer is 63.

Q: Two birds making a nest each made 10 round trips collecting building materials. If the building materials were located 200 miles from where they were building the nest, what is the total distance the birds covered in the trips?
A: In one round trip, traveling to and from the building materials location, one bird covers 2 * 200 = 400 miles. If in one round trip one bird covers 400 miles, in 10 round trips, it covers 400 * 10 = 4000 miles. Since there were two birds collecting the materials, they covered a combined 4000 + 4000 = 8000 miles collecting the building materials in 10 round trips. The answer is 8000.

Q: Jenna is on a road trip. She drives for 2 hours at 60mph. She takes a bathroom break, and then she continues driving for 3 hours at 50 mph. She can drive for 30 miles on one gallon of gas. If one gallon of gas costs $2, how much money does she spend on gas for her trip?
A:
First she drives 2 hours * 60 mph = 120 miles. Then she drives 3 hours * 50 mph = 150 miles. The total miles driven is 120 + 150 = 270 miles. Jenna uses 270 / 30 = 9 gallons of gas. The cost of gas is 9 * $2 = $18. The answer is 18.
