Final answer:
The function V(b) = 500 - 0.5b represents the volume of ketchup left in a dispenser after b burgers are made, starting from 500 fluid ounces. This is a simple linear function that subtracts half a fluid ounce for every burger made.
Step-by-step explanation:
The question is related to the function V(b), which represents the volume of ketchup remaining in a dispenser after b burgers are made. If the ketchup dispenser accurately dispenses 0.5 fluid ounces onto each burger and starts with 500 fluid ounces, the function V(b) can be written as V(b) = 500 - 0.5b. This formula can calculate the remaining volume of ketchup after any given number of burgers has been made.
To find the volume of ketchup left after a certain number of burgers, simply plug in the value of b into the function.
