susie went to the store. she spent half her money on groceries. she spent $13 on paper supplies. she still had 1/4 of the amount she began with. how much did she start with?
Let x = the money she started with
(3/4)x + 13 = x
13 = x - (3/4)x
13 = (1/4)x
13 / (1/4) = x
13 * (4/1) = x
52 = x
To determine the amount Susie started with, we can follow these steps:
1. Let's assume the amount Susie started with is X dollars.
2. She spent half of her money on groceries, so she spent X/2 dollars.
3. she spent an additional $13 on paper supplies.
4. After finishing shopping, she still had 1/4 of the amount she began with, which means she had 1/4 * X dollars left.
5. To find the amount she started with, we can create the equation: X/2 - $13 + 1/4 * X = 0.
We can solve this equation to find the value of X, which represents the amount Susie started with.
