Question: Julia collects old watches. She owns 20 silver watches, and three times as many bronze watches. She decided to buy gold watches to add to her collection, a number that represents 10% of all the watches she owns. How many watches does Julia own after this purchase?
Answer: Julia owns 3 * 20 = 60 bronze watches. 60 + 20 = 80 total silver and bronze watches. 10% of all Julia's watches is 80 * 10 / 100 = 8 watches, and she decided to buy so many gold watches. So in total Julia is in possession of 20 + 60 + 8 = 88 watches. The answer is 88.
[Question]Erin put 16 curlers in her hair. One-fourth of the curlers are small pink ones. There are twice as many medium blue curlers as there are pink ones. The rest are large green curlers. How many large green curlers does Erin have in her hair?
[Answer]There are 16 curlers in all and of them are pink or 16 curlers / 4 = 4 pink curlers. There are twice as many blue curlers as there are pink ones, so there are 4 pink x 2 = 8 blue curlers. Together, there are 4 pink curlers + 8 blue curlers = 12 pink and blue curlers in Erin's hair. The remaining curlers are green, so of the 16 total curlers 12 pink and blue curlers = 4 green curlers are in Erin's hair. The answer is 4.
Q: It takes Jerome 6 hours to run the trail around the park and it takes Nero 3 hours. If Jerome runs at 4 MPH, what speed (in MPH) does Nero run in the park?
A: You can find the distance of Jerome's run by multiplying the time he spends running by his speed: 4 miles / hour * 6 hours = 24 miles. Then find Nero's speed by dividing the distance he runs by the time he spends running: 24 miles / 3 hours = 8 miles / hour. The answer is 8.
Question: 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?
Answer: 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.
[Question]Tamia is making dinner. She is using 5 bell peppers to make her meal. She likes to have a variety of sizes so some will melt and some will be thick enough to eat whole. First she cuts each bell pepper into 20 large slices. Then she takes half those slices and cuts them into 3 smaller pieces each. How many slices and pieces of bell pepper total is Tamia going to add to her meal?
[Answer]First, Tamia cuts the 5 bell peppers into 20 slices each, 5 x 20 = 100 slices. Then, she takes 1 / 2 of those to cut into smaller pieces, 100 / 2 = 50 slices to cut smaller. Tamia takes each of those 50 slices and cuts them into 3 pieces each, 50 x 3 = 150. Tamia is adding 50 slices + 150 smaller pieces = 200 pieces of bell pepper added to her meal. The answer is 200.
[Question]The seats of a bus are arranged in 23 rows of 4 seats. At the start, 16 people climb. At the first stop, 15 people board the bus and 3 get off. At the second stop, 17 people get on the bus and 10 get off. How many empty seats are there after the second stop?
[Answer]
There are 23 * 4 = 92 seats on this bus. After the first stop, there are 16 + 15 - 3 = 28 people on the bus. After the 2nd stop, there are 28 + 17 - 10 = 35 people on the bus. So there are 92 - 35 = 57 empty seats on the bus after the 2nd stop. The answer is 57.
