Question

In the month of January, a certain restaurant claimed it sold 9,000 burgers and expects sales to grow at a rate of 4.8% per month over the next year. Which formula will determine the number of burgers the restaurant expects to sell this year

Answer 1

Answer:

$\sum\limits_{n=1}^{11} 9000(1.048)^n$

Step-by-step explanation:

First month = a = 9000

Common ratio = r = 1 + 0.48 = 1.048

Number of months = n = 11 (Feb to Dec)

Formula to find the number of burgers sold in this year:

$\sum\limits_{n=1}^{11} 9000(1.048)^n$
