11111nata11111 [884]

Answer:

11.5

Step-by-step explanation:

Simple interest formula:

$I=P\cdot r\cdot t,$

where

I = interest

P = principal

r = rate

t = time

In your case,

P = $4,000

I = $4,920 - $4,000 = $920

t = 2 years

So,

$920=4,000\cdot r\cdot 2\\ \\r=\dfrac{920}{2\cdot 4,000}=0.115$

The rate as decimal is 0.115 that is 11.5% as percent
