// quiz1.rs
// This is a quiz 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!
// Put your function here!
fn calculate_apple_price(num: i32) -> i32 {
if num <= 40 {
num * 2
} else {
num
}
}
// Don't modify this function!
#[test]
fn verify_test() {
let price1 = calculate_apple_price(35);
let price2 = calculate_apple_price(65);
assert_eq!(70, price1);
assert_eq!(65, price2);
}
