Question

The book “wrinkle in time” costs $8.05. Of it was increased by 10% what would be the new price?

Answer 1

Answer:
`\$8.855`

Explanation:

The former cost of the book is
`\$8.05`

The new cost of the book is the old cost plus the
`10\%` of
`\$8.05`:

`\$8.05+\$8.05(10\%)`

Since:

`10\%=(10)/(100)=0.1`

We have the following:

`\$8.05+\$8.05(0.1)=\$8.05+\$0.805`

Then, the new price of the book is:

`\$8.855`
