// test1.rs
// This is a test for the following sections:
// - Variables
// - Functions

// Mary is buying apples. One apple usually costs 2 Rustbucks, but if you buy
// more than 40 at once, each apple only costs 1! Write a function that calculates
// the price of an order of apples given the order amount. No hints this time!

fn calculate_apple_price(amount: i32) -> i32 {
    let mut unitPrice: i32 = 2;
    if (amount > 40) {
        unitPrice = 1;
    }
    return amount * unitPrice;
}
// Don't modify this function!
#[test]

    let price1 = calculate_apple_price(35);
    let price2 = calculate_apple_price(65);

    assert_eq!(70, price1);
