Answer:

The required expression is [tex]P(x)=2.5x+100[/tex]

Step-by-step 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.

[tex]4z+100=110[/tex]

[tex]4z=10[/tex]

[tex]z=2.5[/tex]

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

Hence, the required expression is:

[tex]P(x)=2.5x+100[/tex]

Where x is the number of computer she sells.
