mason opened a new electronic store, and his daily sales are modeled by f(x) = 50(1.2)x. determine the rate of growth.

50%
20%
12%
120%

20%

Step-by-step explanation:

To find growth rate in compound growths, we can look at a general formula. Shown below:

Where a is the initial amount

b is the growth factor

x is time

In our formula given, we see that b = 1.2

What growth does this represent??

Well, the amount that is OVER 1, is the growth. Simple!

So, we take the value of b and then subtract 1 from it. Then we multiply that answer with 100 to get a PERCENTAGE GROWTH RATE. Let's do this on b:

b = 1.2

b - 1 = 1.2 - 1 = 0.2

0.2 * 100 = 20

Which is 20%!

So the growth rate is 20%
