Answer:
The fixed fee is represented by "5.75".
Step-by-step explanation:
In this function, the part that represents the fixed fee is the "5.75", this part is called interception or origin, which is a value that stays the same regardless of the number of pounds. Unlike the "4.99X" part, which is going to change depending on the number of pounds. The "5.75" part is never changing, it's a value that always will be charged to the payment.
