Answer:

8%

Step-by-step explanation:

We will use the equation provided to solve this problem.

[tex]I=Prt[/tex]

Lets plug in the values:

[tex]64=800x(1)[/tex]     First, divide both sides by 800.

[tex].08=x(1)[/tex]         Multiply x by 1

[tex]x = .08[/tex]

Now, we multiply .08 by 100 to get our interest rate:

(.08)100 = 8

The interest rate is 8%
