Answer:
d. 0.85m + 2.50
Step-by-step explanation:
In the figure attached, the complete question is shown.
We can see in the table that $2.50 is a fixed charge, that is, it is not modified by any variable. On the other hand, for each travelled mile, the cost of the travel increases $0.85 ($0.75 by mileage charge + $0.1 by city gas tax). Then, if m miles are travelled, the cost of the travel increases 0.85*m
Using exponential function concepts, it is found that the correct sentence is given by:
The temperature difference is reduced by a factor of every 9.7 seconds.
A decaying exponential function is modeled by:
In which:
In this problem, the function is given by:
The decay rate is given by:
Hence, the sentence is:
The temperature difference is reduced by a factor of every 9.7 seconds.
