Answer 1

`30+0.09x`

Here,
`x` denotes number of frosting flowers

Explanation:

Let
`x` denotes number of frosting flowers.

Amount charged by baker for each batch of cupcakes = $30

Amount charged for each frosting flower = $0.09

So,

Amount charged for
`x` frosting flowers =
`\$0.09x`

Therefore,

Total cost of a batch of cupcakes with frosting flowers =
`30+0.09x`
