#### Answer

46.4

#### Work Step by Step

To solve this, you must set up an equation. First, you have to convert 80% to a decimal. So you have to divide 80 by 100. You get .80 because you will move the decimal 2 places to the left. Now, you set up the equation, which is n=58 x .80 So all you have to do is multiply 58 by .80, and you will get 46.4.
