Answer 2

Max has $10. He earns $25.75 for every lawn he mows.

Sasha sells a scarf for $10 and x jackets for $25.75 each.

Explanation:

The expression is:
`25.75x+10`.

This expression represent a situation where a person earns $25.75 per unit, and the person already has $10.

So, all situations that have this characteristics are:

• Max has $10. He earns $25.75 for every lawn he mows.
• Sasha sells a scarf for $10 and x jackets for $25.75 each.

Both situations have as initial condition +$10, and each person earns $25.75 per unit, which is the represented by a variable.

Other options cannot be represented by the given expression, because they don't earn $25.75 per unit of some item, and the initial condition is not +$10.
