// This is a quiz for the following sections:
// - Variables
// - Functions
// - If
//
// Mary is buying apples. The price of an apple is calculated as follows:
// - An apple costs 2 rustbucks.
// - If Mary buys more than 40 apples, each apple only costs 1 rustbuck!
// Write a function that calculates the price of an order of apples given the
// quantity bought.

// Put your function here!
// fn calculate_price_of_apples(???) -> ??? {

fn main() {
    // You can optionally experiment here.
}

// Don't change the tests!
#[cfg(test)]
