I copied the solution and pasted it over my solution because I kept getting an odd error and I still get this error:

error[E0277]: cannot divide f64 by usize
--> exercises/23_conversions/using_as.rs:8:11
|
8 | total / values.len()
| ^ no implementation for f64 / usize
|
= help: the trait Div<usize> is not implemented for f64
= help: the following other types implement trait Div<Rhs>:

<f64 as Div<&f64>>
<&'a f64 as Div>
<&f64 as Div<&f64>>

For more information about this error, try rustc --explain E0277.
error: could not compile exercises (bin "using_as") due to 1 previous error

It doesn't even match line 8 which is just "}".
