Answer:
The function can the fast food chain use to determine its total profit, P(x), after x years :
Total profit after 4 years = $101,851.79
Step-by-step explanation:
Branch A:
First year profit = $50,000
The profit increased by 4% every year
Formula :
So, Total profit after x years =
=
Branch B:
First year profit = $35000
The profit increased by 5.5% every year
Formula :
So, Total profit after x years =
=
Thus the function of total profit of fast food chain :
Now to find total profit after four years .
Substitute x = 4
Hence Option D is correct.
The function can the fast food chain use to determine its total profit, P(x), after x years :
Total profit after 4 years = $101,851.79
