x computers.

Answer 1

The required expression is
`P(x)=2.5x+100`

Explanation:

Consider the provided information.

She makes a base pay of $100 each day and is also paid a commission for each sale she makes.

One day, Lily sold 4 computers and was paid a total of $110.

Let z is the commission for each sale.

Therefore, 4z is the total commission after selling 4 computers.

`4z+100=110`

`4z=10`

`z=2.5`

Therefore, she is earning $2.5 for each computer sold.

Hence, the required expression is:

`P(x)=2.5x+100`

Where x is the number of computer she sells.
