Question

Vanessa spent 4/5 of her money at the bookstore. In total, the books cost $45. How much did she start with?

Answer 1

The money she start with is $25.

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
`x`.

Money spent at the bookstore
`(4)/(5) x`.

Total books cost = $45.

According to question:

`x+(4)/(5)x=45`

⇒
`x+(9x)/(5) =45`

Adding the variables we get:

⇒
`(9x)/(5) =45`

Multiplying both sides by 5 we get:

⇒
`9x=225`

Dividing both sides by 9 we get:

⇒
`x=\$25`

Therefore, the money she start with is $25.
