Question

Julia opened a new flower shop, and her daily sales are modeled by f(x) = 2(1.25)x. Determine the rate of growth.

A.2%
B.125%
C.75%
D.25%

Answer 1

The answer is D) 25%

Answer 2

D. 25%

Explanation:

f(x) = 2 * (1.25)^x

This is in the form

y = a b^x

where b is 1 plus the growth rate

b = 1.25 = 1+growth rate

1.25 = 1 + growth rate

.25 = growth rate

25% = growth rate
