The function rule that represents the situation is p = 6.75 + 0.55t
Writing a function rule that represents the situation.
From the question, we have the following parameters that can be used in our computation:
Fixed price = $ 6.75
Rate = $ 0.55 for each t toppings
The function rule that represents the situation is calculated using
p = Fixed price + Rate * t
Substitute the known values into the equation
p = 6.75 + 0.55 * t
Evaluate
p = 6.75 + 0.55t
Hence, the function rule is p = 6.75 + 0.55t
