Answer:
Hailey's total pay on a day which she sells x dollars worth of computer is ![P(x) = 100 + \frac{x}{40}](https://tex.z-dn.net/?f=P%28x%29%20%3D%20100%20%2B%20%5Cfrac%7Bx%7D%7B40%7D)
Step-by-step explanation:
<em>Given,</em>
Let x represents the total amount of sales per day
Let bp represents her base pay
bp = $100
Let sc represents her sales commission
sc = 2.5% of total amount of sales
sc = 2.5% of x
Let P(x) represent her total pay on a day she sells x dollars worth of computer
To calculate P(x), we make use of the summation of her base pay by her total sales commission.
This is given as
P(x) = base pay + sales commission
or
P(x) = bp + sc
By Substitution of the right values
P(x) = $100 + 2.5% of $x
of $x
![P(x) = 100 + \frac{2.5x}{100}](https://tex.z-dn.net/?f=P%28x%29%20%3D%20100%20%2B%20%5Cfrac%7B2.5x%7D%7B100%7D)
![P(x) = 100 + \frac{25x}{1000}](https://tex.z-dn.net/?f=P%28x%29%20%3D%20100%20%2B%20%5Cfrac%7B25x%7D%7B1000%7D)
![P(x) = 100 + \frac{x}{40}](https://tex.z-dn.net/?f=P%28x%29%20%3D%20100%20%2B%20%5Cfrac%7Bx%7D%7B40%7D)
Hence, Hailey's total pay on a day which she sells x dollars worth of computer is ![P(x) = 100 + \frac{x}{40}](https://tex.z-dn.net/?f=P%28x%29%20%3D%20100%20%2B%20%5Cfrac%7Bx%7D%7B40%7D)
