Jen collects stamps. The first month she added 25 stamps. Six months later, she doubled in number to a total of 98. How many stamps did she have to start with.
800
To find out how many stamps Jen had to start with, let's break down the information given.
We know that after the first month, Jen added 25 stamps. So, if we assume she started with X stamps, then after one month, she would have X + 25 stamps.
We are also told that six months later, she doubled in number and had a total of 98 stamps. This means that after six months, she had 98 stamps, which is twice the number she had after the first month.
Using this information, we can set up an equation to solve for X:
(X + 25) * 2 = 98
First, let's simplify the equation:
2X + 50 = 98
Next, let's isolate X:
2X = 98 - 50
2X = 48
Now, divide both sides of the equation by 2:
X = 48 / 2
X = 24
Therefore, Jen started with 24 stamps.
