Question

Mason opened a new electronic store, and his daily sales are modeled by f(x) = 50(1.2)x. Determine the rate of growth.
A.) 50%
B.) 20%
C.) 12%
D.) 120%

Answer 1

An exponential function may be given by:

f(x) = A(1+r)^x

A is the initial amount and r is a decimal representing the growth rate.

We can see that 1+r = 1.2, and we solve for r:

1 + r = 1.2

r = 0.2

The growth rate is 0.2, or 20%
