Misleading Wording

Quiz one asks for a function that calculates the price of apples. It says if Mary buys MORE than 40 then they will one cost one rustbuck. HOWEVER the function requires that they cost 1 rustbuck for Greater than OR Equal to. This is misleading and I believe it should be changed.

To my understanding the current code is correct.
According to the tests the price for 40 apples is 80 rustbucks, which leads to 2 rustbucks per apple.
If Mary buys more than 40 apples e.g. 41 the expected price is 41 rustbucks, which is 1 rustbuck per apple.

Yes, here's the test function that's being referenced:

rustlings/exercises/quiz1.rs

Lines 22 to 33 in 9a743f8

	#[test]
	fn verify_test() {
	let price1 = calculate_price_of_apples(35);
	let price2 = calculate_price_of_apples(40);
	let price3 = calculate_price_of_apples(41);
	let price4 = calculate_price_of_apples(65);
	assert_eq!(70, price1);
	assert_eq!(80, price2);
	assert_eq!(41, price3);
	assert_eq!(65, price4);
	}

perhaps i was incorrect...

I had the same issue yesterday and had to look into tests after writing my incorrect solution. :)

Though, the issue isn't critical, I'd suggest to change the wording from

// 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!

to

// Mary is buying apples. The price of an apple is calculated as follows:
// - An apple costs 2 rustbucks.
// - However, if Mary buys more than 40 apples, the cost for each apple in the entire order reduces to 1 rustbuck.
