Question

You purchase n cartons of tennis balls at $25 per carton from an online retailer that charges 8% tax and $17 in shipping costs. The expression 25n +0.08(25n) + 17 can be used to represent the total cost.

Answer 1

The expression is
`\$(27n+17)`

Explanation:

The question is Simplify the expression and identify the units

we have

`25n+0.08(25n)+17`

Find the product between 0.08 and 25n

`0.08(25n)=2`

substitute

`25n+2n+17`

Groups terms that contain the same variable

`(25n+2n)+17`

Combine like terms

`27n+17`

The expression above represent the total cost

therefore

the unit is in dollars ($)
