Kelley · Answer 1

growth 30%

Step-by-step explanation:

This is in the form

y = a b^x

Where b is the growth rate

b>1 it is growth

b<1 it is decay

1.3 >1 so it is growth

b-1 =.3 so the growth rate is. 3 = 30%

Pennington · Answer 2

Growth, rate: 30%

Step-by-step explanation:

Since 1.3 > 1,

It's growth

(1.3 - 1) * 100

= 30%
