Question

How many persons are in the line? Ashley is in the line to buy a ticket. There are twice as many people in front of Ashley as there are behind her. How many people are in the line, if Ashley is the 7th person ​

Answer 1

Answer:

I am pretty sure there are 10 people in line.

Since Ashley is the seventh person in line, we can deduce that there are 6 people in front of her.

Since the amount of people in front of her is "twice as many people as there are behind her," we can divide the value of the people in front of her in half to get the value of people behind her.

6/2 is 3, so there are 3 people behind Ashley.

Now, lets add the amount of people in front of Ashley to the amount of people behind her. 3 + 6 = 9, and since Ashley is also in the line, we should add 1 to the sum.

9 + 1 = 10, so there are 10 people in the line.
