c ÷ 25 = 100


c × 25 = 100


c + 25 = 100


c - 25 = 100

Answer 1

The answer is c- 25 = 100

Answer 2

For this case, we must pose an equation that represents the situation of Sammie, to find the amount of money he had initially.

Let variable "c" be the amount of money Sammie had in her account before she took the money out.

So, if I take $ 25 of that amount "c" we have:

`c-25`

Now, if you have $ 100 left, after took the money out, then we have:

`c-25 = 100`

Thus, the equation that represents Sammie's situation is:

`c-25 = 100`

Answer:

`c-25 = 100`
