[Question]A highway is being extended from its current length of 200 miles up to 650 miles. 50 miles are built on the first day, and three times this amount are built on the second day. How many miles still need to be added to the highway to finish extending it?
[Answer]The length of the highway that needs to be constructed is 650 200 = 450 miles. After the first day, there are still 450 50 = 400 miles that need to be constructed. On the second day, 50 miles * 3 = 150 miles are added to the highway. This means that 400 150 = 250 miles still need to be added to the highway. The answer is 250.

[Answer]If the number of candies was 300, and 40% percent were sour, then there were 40 / 100 * 300 = 120 sour candies. The number of good candies was 300 - 120 = 180. The number of people who received candy is Henley, 1 + 2 brothers = 3 people. if they divided the good candies equally, each person got 180 / 3 = 60 candies. The answer is 60.
