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

Answer:

c) 12%

Foley · Answer 2

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%
