Answer:
The money she start with is <u>$25</u>.
Step-by-step explanation:
Given:
Vanessa spent 4/5 of her money at the bookstore.
In total, the books cost $45.
Now, to find the money she start with.
Let the money she start with be
.
Money spent at the bookstore
.
Total books cost = $45.
According to question:
![x+\frac{4}{5}x=45](https://tex.z-dn.net/?f=x%2B%5Cfrac%7B4%7D%7B5%7Dx%3D45)
⇒![x+\frac{9x}{5} =45](https://tex.z-dn.net/?f=x%2B%5Cfrac%7B9x%7D%7B5%7D%20%3D45)
Adding the variables we get:
⇒![\frac{9x}{5} =45](https://tex.z-dn.net/?f=%5Cfrac%7B9x%7D%7B5%7D%20%3D45)
<em>Multiplying both sides by 5 we get:</em>
⇒![9x=225](https://tex.z-dn.net/?f=9x%3D225)
<em>Dividing both sides by 9 we get:</em>
⇒![x=\$25](https://tex.z-dn.net/?f=x%3D%5C%2425)
Therefore, the money she start with is <u>$25</u>.
