Our answer will be 96/800, which is interest rate/total.

 

That will get us 0.12, or 12%

 

Hope this helped!

Whoa, Cal....you were right in the  first place  !!!

 

I = Prt

 

96 = 800 * r * 5

 

96 = 4000 * r    

 

96 / 4000  = r  = .024 =  2.4%

 

[   19.2 / 800  = .024  ]  

 

 

cool cool cool
