Clarified hint text

[JanB1]

The hint says that u32 would be more fitting for the prices. But this is only true for the original price and thus as an extension the parameters of the functions, not the type of the return value of sale_prince, as this could be negative for original_price values between 0 and 10 (specifically it will be negative for the input values of 1, 2, 4, 6 and 8).

Code for the exercise:

fn main() {
    let original_price = 51;
    println!("Your sale price is {}", sale_price(original_price));
}

fn sale_price(price: i32) -> i32 {
    if is_even(price) {
        price - 10
    } else {
        price - 3
    }
}

fn is_even(num: i32) -> bool {
    num % 2 == 0
}

PS. I know this might be pedantic and certainly will be very far down on the list of priorities, but I have stumbled over this hint multiple times, and the first time I encountered it I thought I was missing something and was quite stumped, just to figure out that the comment possible meant something else.
