Question

bernards stock investments went up by $10,000 in a single day. however, a day after he made all that money, his investments lost half their value, making them worth only $55,000. how much were they worth originally? after you enter your answer press go. $

Explanation:

Step1: Let the original value be $x$.

The value after going up by $10000$ is $x + 10000$.

Step2: After losing half the value, it becomes $\frac{x + 10000}{2}$.

We know $\frac{x + 10000}{2}=55000$.

Step3: Solve the equation for $x$.

Multiply both sides by 2: $x + 10000=110000$.
Then subtract 10000 from both sides: $x=110000 - 10000$.

Answer:

$100000$
