To solve this problem, we need to determine the value of x, which represents the number of snowballs Janet made.
We know that Janet's brother made 150 snowballs, and Janet made 25% of the total number of snowballs.
Let's set up the equation:
Janet's snowballs = 25% of total snowballs
x = 0.25 * (x + 150)
Let's simplify and solve for x:
x = 0.25x + 0.25 * 150
x = 0.25x + 37.5
To isolate x, we subtract 0.25x from both sides of the equation:
x - 0.25x = 37.5
0.75x = 37.5
To solve for x, we divide both sides of the equation by 0.75:
x = 37.5 / 0.75
x = 50
The value of x is 50.
#### 50
The answer is: 50
