Milly is making croissants. She needs to fold the dough 4 times, which takes 5 minutes each time, then let it rest for 75 minutes each time. If mixing the ingredients takes 10 minutes and baking the croissants takes 30 minutes, how many hours does the whole process take?
Let's think: First finding the time to fold the dough and let it rest one time: 5 minutes + 75 minutes = 80 minutes. Then find the total time spent folding and resting the dough: 80 minutes / time * 4 times = 320 minutes. Then add the mixing and baking time: 320 minutes + 30 minutes + 10 minutes = 360 minutes. Then divide that number by the number of minutes per hour to find the total time in hours: 360 minutes / 60 minutes / hour = 6 hours.. The answer is: 6.

300 cows in a field are made up of male and female cows. There are twice as many females as males. Half the females are spotted, and half the males have horns. How many more females with spots are there than males with horns?
Let's think: There are (300 / 3) x 2 = 100 x 2 = 200 females cows in the field. There are 200 / 2 = 100 male cows in the field. 200 / 2 = 100 female cows are spotted. 100 / 2 = 50 male cows have horns. There are 100 - 50 = 50 more females with spots than males with horns.. The answer is: 50.

Trent walked 4 blocks from his house to the bus stop. He rode the bus 7 blocks to the library. Later, he came home the same way. How many blocks did Trent travel in all?
Let's think: On the way to the library, Trent went 4 blocks + 7 blocks = 11 blocks. Trent came home the same way so he went 11 blocks + 11 blocks = 22 blocks.. The answer is: 22.

James has to refuel his plane. It used to cost $200 to refill the tank. He got an extra tank to double fuel capacity. Fuel prices also went up by 20%. How much does he pay now for fuel?
Let's think:
The cost to fill a tank went up 200 * .2 = $40. So it cost 200 + 40 = $240 to fill the tank. That means he now pays 240 * 2 = $480.. The answer is: 480.
