Question

Answer 1

Josh bought a new book that cost $13.95 and some bookmarks

Let the cost of the bookmarks be b.

It then followed that the cost of the new book plus the cost of the bookmarks will give the total cost of $20.30

Mathematically,

`\text{ \$13.95+b=\$20.30}`
`\begin{gathered} b=\text{ \$20.30-\$13.95} \\ b=\text{ \$6.35} \end{gathered}`

Hence $13.95+b=$20.30; b=$6.35 is the answer, the third option
